It is important to quickly collect a complete history, conduct diagnostics and make an accurate diagnosis. Self-medication without contacting a specialist causes a blurred clinical picture and errors in therapy.

Stain classification

Itchy rash on ankle

The spot is characterized by a change in the color and structure of the skin in a certain area. There are two groups of spots depending on the characteristics of the changed area:

Vascular formations. They are distinguished by a red, purple, brown, yellow or blue tint. Vascular formations are divided into:

• spots associated with temporary expansion of the lumen of blood vessels (allergic, caused by a burn, infectious process);
• the result of constant disruption of the structure of blood vessels (spider veins);
• hemorrhagic spots, a consequence of blood leaking from small vessels.

Pigment formations. Caused by changes in the amount of coloring pigment in the skin, both an increase and a decrease in its level. With insufficient melanin content, whitened areas of the skin appear; with excess production, areas that are darker than the rest of the skin appear. The area may be round or have vague outlines. The following types of age spots are distinguished:

• moles – characterized by a dark or reddish color;
• melasma - appears during pregnancy or certain pathologies of internal organs;
• freckles – typical for people with fair skin and can be located on different parts of the body;
• lentigo - spots of a dark shade, characteristic of the elderly and children under 10 years of age.

Sometimes secondary hyperpigmentation appears as a result of hair removal, depilation, laser exposure, or lack of vitamins in the body.

Main provoking factors

Red spots on legs

There may be several reasons for the development of such anomalies:

• Infectious process. A red spot on the lower leg in this case is a sign of an infection, for example, erysipelas. The development of pathology provokes the proliferation of streptococci. The skin begins to itch, a feverish state develops, and signs of intoxication are observed: headache, general weakness, apathy, swelling). The skin is hot, and pressing is accompanied by severe pain. This indicates the spread of pathology.
• Allergy. Irritation can be either widespread or localized. Allergic reactions are usually triggered by food and cosmetics. Sometimes allergies to synthetic fabrics occur. In addition to discoloration and itching, the affected area swells and peels.
• Mycosis (fungal infection). It most often affects the feet, but in advanced cases it spreads to the legs. The disease is characterized by a rash with clear localization and peeling. The affected area may itch. General health the patient rarely changes. A type of pathological process is pityriasis rosea. Its peculiarity is that there is no risk of infection for other people. Pityriasis rosea develops when the immune system is weakened.
• Psoriasis. Location: areas of the extensor surfaces of large joints (for example, in the knee area). Other areas of the body, the facial area, are affected, and general health worsens.
• Eczema. Occurs in both acute and chronic form. The rash occurs in the form of spots, blisters, papules. The affected skin becomes dry or has weeping areas. In advanced cases, the integrity of the skin is compromised, especially in places where it is subject to friction.
• Atopic dermatitis. Pathological process of a chronic nature. The reason for its appearance is the special sensitivity of a person to the influence of certain factors.
• Varicose veins. Spots appear due to impaired blood supply to tissues. There may be numbness, swelling of the lower extremities, and deterioration in general condition. If you have varicose veins, you should immediately consult a specialist.

Red spots on the lower leg occur in diabetes mellitus as a result of metabolic disorders and permeability of the walls of small vessels. If the disease is not treated on time, there is a risk of developing complications that are dangerous to health and life in general.

Changes in metabolic processes are characteristic of hemosiderosis.

The first sign of the disease is a small dot with a dark (brown) tint.

Then other rashes may appear. The pathological process is caused by excessive accumulation of the dye hemosiderin. This occurs due to impaired functioning of the liver and hematopoietic system.

Other provoking reasons

Excessive red spots on the legs

If spots appear and disappear, perhaps this is a consequence of vegetative pathologies nervous system. It is responsible for the narrowing and expansion of the lumens of blood vessels. Such disruptions in the body can be associated with emotional fatigue, physical activity, anxiety, and high ambient temperatures.

Changes in skin color can be caused by the development of measles or rubella. With measles, small spots appear first. Then they merge, forming more extensive formations. There is no clear localization for measles; the spots spread throughout the body.

The development of rubella most often occurs in children under 5 years of age. The spots do not tend to merge and appear as a small rash.

Depending on the type of infection, an antibacterial or antiviral drug is prescribed.

Sometimes an adult turns to a specialist with complaints about the appearance of multiple spots throughout the body, including on the lower extremities. There are no other manifestations general. The cause may be syphilis, such rashes are characterized by a pink or red tint.

Diagnostics

Doctor examining leg to make a diagnosis

If red spots appear on the lower legs, they do not itch or hurt, you should not self-medicate and try to restore the previous skin color with the help of traditional medicine. It is necessary to make an appointment with a doctor to rule out serious illnesses.

You can contact a dermatologist or therapist. Typically, a specialist prescribes the following diagnostic procedures:

• general blood and urine examination;
• blood chemistry;
• determination of blood sugar levels;
• bacterial culture;
• ultrasonography.

A thorough external examination and laboratory diagnostic data will allow you to determine the diagnosis and treatment regimen.

Features of treatment

Effective ointments for rashes on legs

If an infectious process is detected, treatment with antibacterial, antiviral, and antifungal drugs is necessary, depending on the type of pathogenic microflora.

If pityriasis rosea is detected, it is necessary to take care of strengthening the immune system and quality nutrition. At the same time, it is important to limit the consumption of foods that can provoke unwanted skin reactions.

If an allergy is detected, the irritating agent must be identified. The use of cosmetics with fragrances should be avoided and contact with household chemicals should be limited.

If allergic reactions develop, antihistamines and enterosorbents are prescribed.

Dysfunction autonomic system does not require specific treatment. Contrast baths and physical activity will come to the rescue. Stressful situations and overwork should be avoided.

Eczema and psoriasis require an integrated approach to therapy. It includes the use of local remedies and physiotherapy. For psoriasis, the use of biological agents is indicated. Their action is aimed at stimulating the function of T-lymphocytes, which relieves inflammation and other symptoms of the disease. For eczema, hormonal medications are prescribed.

For varicose veins, angioprotectors, antiplatelet agents, and drugs that improve microcirculation of venous blood are prescribed.

If drug therapy does not produce results, surgical intervention is required.

Regardless of the cause of the pathology, the choice of medications is the competence of a specialist. You should not choose antibiotics yourself. They can lubricate clinical picture and delay the healing process.

If a red spot appears on your lower leg, it itches, begins to grow and peel, the redness increases, you should definitely visit a doctor and not self-medicate.

This is especially important if the skin is hard and rough, and the lower leg begins to hurt and swell. The sooner the cause is identified and treatment is prescribed, the faster a complete recovery will occur.

Typically, such deviations worry women very much, while men are less worried about this. But even such manifestations can be dangerous and cause quite significant damage to the body, especially without timely treatment and diagnosis.

Quite often people notice small red dots on their legs. Such rashes usually raise many questions, and very often full diagnostics it is impossible to say why such a pathology arose.

These manifestations are divided into two groups:

• the first is caused by diseases of the body;
• The second reason is external influences.

2 Possible diseases

Diseases that cause such symptoms belong to the first group, among them:

• pityriasis rosea;
• vasculitis;
• systemic lupus erythematosus (vascular form);
• eczema;
• syphilis;
• chronic allergic or autoimmune processes.

External causes that can cause such disorders belong to the second group of reasons:

1. Bites of various blood-sucking insects, poison and toxins that are in their saliva.
2. Allergic processes that arise as a result of the influence of a certain substance to which an allergic reaction develops.
3. Frequent or too strong exposure to ultraviolet radiation, which negatively affects the skin and vascular wall, causing a red spot(s) to appear on the skin.
4. Aggressive influence chemical substances, which, seeping through the skin, cause harm to the vascular wall.

If a rash was noticed, but after some time it went away on its own, in any case, you should consult a doctor and correct diagnosis, since when various diseases the spots may pass, but the risk of complications and recurrence of the disease remains. This may be dangerous to human health.

Quite often, syphilis can manifest itself in this way, which without timely treatment and diagnosis can lead to death.

This is often how various inflammatory skin diseases manifest themselves, such as psoriasis or eczema. After diagnosis, long-term, timely treatment is necessary, without which the development of the disease will continue.

Small red dots on the legs below the knees are often caused by various autoimmune processes, which include systemic lupus erythematosus, vasculitis, and rheumatism.

If an autoimmune process is suspected, the patient will face not only long-term treatment, but also a complete lifestyle change to stabilize the condition. Without this, negative symptoms will intensify until they cause irreversible damage to the body, which can be fatal.

It is even possible to take immunosuppressants that can reduce the strength of the autoimmune process and help patients more easily tolerate the course of the disease.

To solve problems with the second group, it is important to isolate the allergen, aggressive substance or uncomfortable clothing that will cause bruising when worn.

A fungal infection such as pityriasis rosea causes similar points on the legs, but the patient in this case is contagious to others. For proper treatment and prevention, antifungal drugs are needed, which can almost completely get rid of pityriasis rosea. Only for the duration of treatment is it necessary to completely isolate the patient from society, including from the family.

In women, the causes of red spots on the legs include: minor damage skin that occurs, for example, when shaving your legs. After several uses, the razor is no longer so sharp; serrations appear on it, which do not cut the hair, but tear it off, causing various damages, microcracks. Small red spots appear that will go away a few days after shaving. Timely replacement of blades easily solves this problem.

One of the reasons may be varicose veins veins The first symptoms of this disease are redness of the legs below the knee. Since varicose veins are quite dangerous disease, it is very important to consult a doctor in a timely manner. This disease is especially dangerous for those who stand on their feet for a long time.

Atopic dermatitis can cause red patches that become enlarged, flaky, and itchy. Such dermatitis can develop as a result of the action of various allergic, nervous and other groups of pathogens.

The same symptoms will appear with psoriasis, only over time the spots will begin to become covered with a white coating. Psoriasis is a chronic non-infectious inflammatory disease. A person who is sick with it cannot infect others. This disease has been treated for a long time; no cases of complete recovery have been identified, but there is always the opportunity to stabilize and maintain the condition at a certain level.

Quite often, psoriasis can develop in people who come into contact with various chemical irritants. Psoriasis can be a consequence of a strong autoimmune process in the body.

The disease usually appears in young people aged 15-25 years. At this time, the first symptoms appear.

Now you know what red dots on your legs can mean. Very often, when red spots appear on the legs, people begin to take antiallergic drugs (antihistamines), which is extremely dangerous to do without consulting a doctor. Self-treatment may cause the appearance unpleasant symptoms or blur the clinical picture, after which the doctor will not be able to make a correct diagnosis. Timely diagnosis and proper therapy can help completely get rid of the disease or stabilize the patient's condition.

The skin is the body’s first line of defense from unfavorable external stimuli; it also reflects internal ill-being.

The appearance of areas on the skin that differ in color and structure, which, moreover, can become covered with blisters, peel and itch, does not go unnoticed. Stains may be different sizes – small rash and skin defects of large diameters. If they also itch, they cause significant discomfort. To quickly get rid of this, it is necessary to find out the origin of the spots and carry out treatment.

Nervous Shocks, stress, physical overload, exposure to high temperatures (bath) can manifest as reddish-pink itchy blistering rashes (cholinergic urticaria). A very rare form of urticaria, it is even less common in the lower part of the body. In addition to a tendency to allergies, a person must have intolerance to acetylcholine, an endogenous substance that is intensely released in any person during nervous and physical stress.

The cause of the appearance of itchy red spots on the lower extremities may be a violation of arterial or venous circulation in this area ( varicose veins).

Such rashes are typical for diabetics ( initial stage angiopathy), they can also occur in people with liver disease.

The cause of a red spot on the leg may be erysipelas However, such spots do not itch. In this place, pain and burning are more likely to be felt, but sensations are an individual matter.

Pityriasis rosea– pink spots unknown etiology, as a rule, they do not itch much.

Autoimmune diseases may be accompanied by patchy rashes (idiopathic urticaria). The history of such patients almost always includes allergies.

Spots on the skin of the legs may appear after depilation and other mechanical influences on the skin, such as tight clothing or shoes.

Pigment spots that itch require medical diagnostics, either the itching is not related to pigmentation, or the pigment spot has signs of degeneration, if it, moreover, grows in size, bleeds, and has a multi-colored color.

In a child, spots on the legs most often have an allergic etiology, or are caused by infections - enterovirus, chickenpox, measles, rubella. True, the rashes are located not only on the legs, but throughout the body and the rash, as a rule, is noticed first on the face.

A rash on the legs and buttocks of a child may be one of the symptoms of infectious meningitis.

A child can also have lichen and other dermatomycoses. Emotional outbursts nervous tension It can also result in itchy rashes on the child’s limbs. Much less often, however, spots may appear in childhood due to any other reasons described above.

The pathogenesis of the appearance of allergic spots is considered as the formation of a detailed immune response to irritants upon direct contact of a skin area with it (allergic contact dermatitis) or when an allergen gets inside (food, drug allergy). In the first case, the main pathogenetic links are the reaction of lymphocytes and macrophages, which accumulate in areas of inflammation; in the second, the main role belongs to antibodies synthesized in response to the appearance of antigens. In any case, immune effector cells responsible for protective functions leave the bloodstream and, accumulating on the surface of the skin, cause vasodilation, hyperemia and severe itching.

In the pathogenesis of rashes due to systemic pathologies, for example, liver dysfunction, the main links are insufficient purification of the blood from toxins. Availability of common chronic diseases, nervous and physical overload, hormonal changes have a detrimental effect on work immune system. In each specific case, the pathogenesis of rashes is individual.

The appearance of vascular spots can be triggered by temporary dilation of blood vessels - a sensitization reaction to an irritant, infection. Systemic chronic diseases cause constant expansion vessels - so-called spider veins (hemangiomas) appear.

As a result of rupture of blood vessels, hemorrhagic spots are formed, in other words, bruises of various sizes - from pinpoint hemorrhages (petechiae) to hematomas of very impressive sizes.

The statistics of diseases that may be accompanied by the appearance of itchy spots on the skin of the lower extremities is very extensive. Probably every person has encountered this phenomenon at least once in his life. According to the World Health Organization allergic history is currently present in a third of the world's population, the number of allergy sufferers is growing and it is expected that in a couple of decades every second person will suffer from allergies.

The prevalence of fungal infections is estimated in various sources from 10 to 20% and also tends to increase, like others skin diseases, which can also appear on the skin of the lower extremities.

Lichen planus is a fairly common pathology. Female adults of any age are most susceptible.

Gibert's disease (pityriasis rosea) is a fairly common pathology in people over 20 years of age; after 40 years of age it is very rare. People who have suffered from acute respiratory viral infections mainly fall ill, so a viral etiological hypothesis is being considered.

Varicose veins of the legs are very widespread, its symptoms (according to various sources) are present to a greater or lesser extent in almost 70% of women and more than 50% of men in developed countries.

Liver diseases, diabetes mellitus, autoimmune diseases also very common skin rashes sometimes they are the first signs of their presence.

Symptoms

Rashes on the legs can be caused by various reasons and, accordingly, their appearance and the accompanying symptoms also differ.

The first signs of an allergy that attract attention are itching and the appearance of spots. Sometimes single spots appear, sometimes the entire surface of the skin is covered. It’s hard not to notice if the spots that suddenly appear on your arms and legs are itchy. A pinkish-red, raised, unevenly distributed rash is allergic urticaria. It is accompanied by severe itching, swelling, appears instantly and, when the allergen is eliminated, can disappear quite quickly without treatment. But in severe cases the rashes merge, forming an itchy, continuous affected area. The skin over it becomes dry and thin, cracks when scratched, and acquires a bluish-purple color. The patient may experience shortness of breath, a decrease in blood pressure, fever, or fever. Such patients require mandatory medical examination and are sometimes hospitalized.

Allergic contact dermatitis also manifests itself as rashes that are local in nature. In places of contact with the allergen, the red spots on the legs itch, then begin to get wet and crack. Later spot dries out and peels off.

Allergic skin reactions also appear in the form of dry, crusty spots ranging from pink to bright crimson. Itching can be moderate, and when it comes into contact with clothing, it may intensify.

Rough spots on the legs also itch with atopic dermatitis. However, with this pathology, the legs are not the main location; when the rash appears on the legs, it is already present almost everywhere on the body.

Insect bites are accompanied by severe itching, and in allergy sufferers a large, swollen red spot appears at the site of the bite.

Red spots on the legs itch and peel off due to dermatomycosis. First signs fungal infection smooth skin - a very itchy red spot. It grows quite quickly and becomes lighter in the center and begins to peel off, has a clear border (trichopytosis).

Caused by fungi and can be located on smooth skin, microsporia is a pink, flaky, rather big spot rounded in shape with a clear roll-like edging of a darker color.

It is extremely rare that pityriasis versicolor or versicolor versicolor can be localized on the legs. Yellowish round spots, covered with pityriasis scales, eventually merge into large formations with scalloped edges; their color can range from creamy beige to olive brown. On a tanned body they look lighter, on a pale body - vice versa. This form of mycosis is characterized by slight itching.

Lichen planus is a cluster of purple nodules that coalesce into a large shiny spot irregular shape, slightly protruding above the surface of the skin. On the lower extremities it is usually localized on the inner skin of the thighs and the frontal skin of the lower leg. Blisters may form on the spots (pemphigoid form), and they may peel off (erythematous). This lichen manifests itself in quite a variety of ways; it can be suspected if a large spot on the leg itches. However, the final verdict is up to the doctor.

The disease is characterized by severe itching, especially the warty form. In the atrophic form, the pearly white spots on the legs itch. The rash may be localized in different places, not only on the skin, but also on the mucous membranes.

If a red round spot on your leg itches, it can be a symptom of both lichen and diabetes. Especially if it occurs at the site of a wound or scratch that does not heal for a long time. Additional symptoms motivating people to get tested are constant thirst, nocturia ( frequent urination at night), poor epithelization of skin injuries.

Diabetic dermopathy is common in people suffering from this disease. The spots are located on the front of the lower leg, symmetrically on both legs. The color is brownish-red, the diameter at first does not exceed a centimeter. Over time, the size of the spots increases, and areas of dark atrophied skin cover an increasingly larger area. Itching is moderate. They are more common in older male diabetics.

Diabetic men are more likely to experience the skin manifestation of the disease, Darier's granuloma annulare, although not all experts agree that this disease is caused only by diabetes. The rashes look like small dense pinkish nodules with raised edges. They tend to merge, forming ring-shaped patterns on the body. Subjective symptoms are usually not too disturbing, however, there may be minor pain. Diabetics can be bothered by skin itching even without rashes, so when a granuloma appears, complaints of itching arise. This skin pathology can appear not only in diabetics; allergy sufferers are also at risk (among them there are more children aged 3-10 years and adult women). Sometimes Darier's granuloma annulare occurs after sulfonamide therapy. Favorite places for rashes on the legs and arms are the feet and hands, and can also be located on the body.

Depigmented areas of the skin (vitiligo) are usually not accompanied by itching, however, diabetics who are prone to the appearance of these skin defects may experience the feeling that white spots on the legs are itching.

Yellow spots localized on the back of the knees - diabetic xanthoma, blistering spots on the skin of the feet and fingers - diabetic blister (a rare manifestation of diabetes, appears suddenly and also goes away on its own).

Vascular insufficiency often manifests itself in the legs. Red spots initially in the form spider veins appear in the knee area and on the skin of the lower leg, the spots itch, not too much and not always. Additionally there are nagging pain and a feeling of heaviness in the legs. If the trophism of arterial vessels is impaired, the skin around the spots has pale look, its surface is cold, sensitivity to pain and contrast temperature is reduced. More pronounced itching is characteristic of venous insufficiency, and the skin becomes dark shade, swollen, covered with brownish-purple spots.

When brown spots on the legs itch, this may be a manifestation of liver pathologies. In this case, the itching is not caused by spots that have appeared, but by stagnation of bile or bilirubin, which is eliminated through the skin when the liver cannot cope with its utilization. Itching accompanies many liver diseases and is one of their first signs. As well as skin manifestations. It can be constant and in the form of attacks. The skin of the extremities is a favorite place for itching and rashes.

Xanthomatous rash - yellowish round small spots that itch on the legs, arms, and maybe all over the body.

Spots formed in cases of persistent vasodilation (telangiectasia) are also one of the symptoms of liver disease. True, in this case they usually appear on the legs last.

Minor hemorrhages (hepatic purpura) and multiple rashes on the skin and mucous membranes are also characteristic of liver pathologies. They do not disappear when pressed. There are also quite large hemorrhages. Patients often experience bleeding from the nose and other natural orifices.

Spots on the legs may be symptoms of psoriasis. The itching can be severe and almost unnoticeable, depending on the form of the disease. Such spots are located on the extensor areas, for example, the knees. If in this place dry spot your leg itches, this could be the beginning of vulgar psoriasis. The spot is raised above the level of healthy skin, and the area surrounding it is inflamed. The spot itself in the center is covered with grayish or whitish dry scales. Tend to grow and merge with similar formations. Usually such rashes occur in other places, for example, elbows-knees or palms-soles.

Atypical types of psoriatic plaques are large shiny bright red spots located on the inner thighs and other skin folds, signs of the inverse form of the disease.

Localized on the thighs guttate psoriasis, more often appearing in children and young people after a sore throat. The lower legs, ankles and instep of the foot are favorite areas for warty psoriatic rashes. Round papules merge into plaques that encircle these areas of the legs. The same “bracelets” can usually be found on the wrists.

Large round and rough itchy spots on the legs may have herpetic etiology.

After examining and interviewing the patient, based on the suspected causes of the rash, the doctor will prescribe laboratory tests. You will definitely need to do a clinical and biochemical blood test, as well as a glucose test; general analysis urine. If infection is suspected, culture analysis of scrapings from the spots. A biopsy of the affected areas of the skin and its microscopic examination, dermatoscopy. Allergic contact dermatitis for nickel intolerance is determined by the dimethylglyoxime test. By using immunological tests blood can identify allergens. Cholinergic urticaria is diagnosed using a provocative test with an acetylcholine analogue.

Other instrumental diagnostics will be carried out as necessary: ​​angiography of the vessels of the extremities, ultrasound examination of the vessels, liver, thyroid gland. After conducting examinations, differential diagnostics are carried out based on their data and a final diagnosis is established.

Treatment for itchy spots on legs

Since rashes are a symptom of various diseases, then therapeutic measures carried out to relieve the underlying disease and alleviate the patient’s condition - eliminating itching and healing the surface of the skin.

In case of allergies, it is mandatory to identify and eliminate the allergen and adhere to a hypoallergenic diet. Enterosgel is included in the treatment regimen as a detoxifying agent to cleanse the blood and intestines of toxic substances and allergens. The active component of the drug, polymethylsiloxane polyhydrate, has the ability to absorb and bind metabolites of incomplete metabolic reactions, toxins, opportunistic and pathogenic microbes, eliminating them with feces from the body. At the same time, without interfering with the vital activity of beneficial microorganisms in the intestines. As a result of the detoxifying effect of Enterosgel, the activity of immune cells is stabilized. The sorbent does not enter the general bloodstream. Contraindicated only in acute intestinal obstruction. Approved for use by pregnant and lactating women, in pediatric practice. A side effect may be constipation. Take orally with enough water to swallow, no less than 90 minutes before taking medicine or food or two hours after. Dosage: 5 g (teaspoon) twice a day for children under three years of age; the same single dose given only three times a day between the ages of three and five years; from five to 14 years – 10 g (dessert spoon) three times a day; patients over 14 years of age - dose 15 g (tablespoon) three times a day.

Sometimes this is enough. If necessary, drug therapy is used. Single spots that appear at points of contact with the irritant are treated using local non-hormonal ointments, For example, Fenistil gel. The active ingredient dimethindene maleate easily penetrates the skin, has an antiallergic effect by blocking H1-histamine receptors, reduces irritation, inflammation and itching, and begins to act a few minutes after application. Has a cooling and local anesthetic effect. Do not apply to large affected areas; after application, avoid exposure to sunlight. It is not teratogenic and can be used on small areas of the skin by pregnant and lactating women. Patients over two years old can use it two to four times a day; those under two years old can only use it as prescribed by a doctor. For extensive lesions, it is used in combination with the oral form of the drug - drops or capsules. Drops can be given to children with one month old, up to a year prescribed single dosage from three to ten drops, taken three times a day. Children from one to three years old take 10-15 drops three times a day; from three to 12 years – 15-20; older – 20-40. Can be divided daily dose in two doses, and the evening dose can be twice as high as the morning dose. Capsules are taken by patients aged 12 years and older.

Atopic dermatitis in children from three months of age and adults is treated with cream Elidel. Anti-inflammatory effect active substance(pimecrolimus) is based on the release of pro-inflammatory mediators and cytokines from T lymphocytes and mast cells. By inhibiting the activity of calcinervin, it suppresses the activity of immunocytes of the skin. It does not provoke the development of atrophic processes, the effect is comparable in intensity to clobetasol derivatives. Can be used in long courses.

The cream is easily rubbed twice a day into damaged areas of the skin. It is used at the first signs of atopic dermatitis; when used for a year, it prevents relapses.

Cholinergic rashes are a reaction to an endogenous substance (acetylcholine) formed in the patient’s body under the influence of certain factors. Therefore, antihistamines are not effective in this case; mainly, local drugs with belladonna extract or with atropine. They are applied to spots once or twice a day. Belladonna extract has a pronounced anticholinergic effect. The active ingredients of the extract - alkaloids atropine, scopolamine, hyoscyamine - bind M and H cholinergic receptors, thereby reducing their sensitization to acetylcholine, and also blocking cholinergic nerve impulses.

Combined treatment gives a good effect - local remedies for allergies + oral antihistamines. It is preferable to use second-generation drugs internally that do not have the sedative properties of drugs belonging to the first generation, for example, Loratadine. Effective for allergic urticaria and dermatitis caused by various allergens, including - medicines and bites of blood-sucking insects. It is fast-acting; within half an hour after starting the treatment, the rashes stop itching and inflammatory manifestations decrease.

In cases of ineffectiveness of antihistamines, hormonal drugs of local and systemic action are prescribed. They are taken only as prescribed by a doctor and used in short courses, since they have many impressive side effects, then, after the patient’s condition has improved, they are “followed up” with antihistamines, anti-inflammatory or folk remedies.

For spots caused by liver pathologies, diabetes mellitus Treatment of the underlying disease is prescribed in combination with detoxifying (Enterosgel) and antiallergic drugs.

Dermatomycoses are treated with fungicidal ointments, tablets or combinations thereof, dermatitis caused by viruses or bacteria, respectively, antiviral and antibacterial drugs. The success of treatment depends entirely on correct and timely diagnosis.

The treatment regimen includes vitamins and vitamin complexes, with an emphasis on ascorbic acid and B vitamins. Such products help restore the body’s defenses and increase its own resistance.
