A rash in the armpit is an unpleasant phenomenon that not only spoils the appearance of the skin, but also sometimes signals the development of a serious illness. Usually, armpit rashes are accompanied by intense itching and irritation of the skin, which causes severe suffering to the person.

The pathological condition of the skin is most often observed in women and children; it is extremely rarely diagnosed in the elderly.

Therapy consists primarily of treating the affected area of ​​the body with external medications; in some cases, systemic medications are used or surgery is prescribed.

Pimple on the armpit: when should you see a doctor?

When a rash appears, most people are hesitant to seek medical help. Pathological elements either go away on their own or can be easily treated at home.

But there are a number of cases in which it is recommended to consult a doctor:

• a sharp increase in pustule size;
• spread of rashes to neighboring areas;
• increased itching and pain;
• deterioration of general condition, increase in temperature.

In such cases, it is necessary to completely cancel home therapy.

The pathological phenomenon is painful and painful, as in most cases it is accompanied by burning and unbearable itching.

Different factors can provoke armpit rashes in adults and children.

Factors causing rash in adults

A rash under the armpit in adults appears under the influence of two types of factors: those caused by non-compliance with hygiene rules and those signaling the development of pathology. The first type includes the following factors.

1. Ignoring hygiene rules. People who are obese, have hormonal imbalances in the body, or engage in heavy physical labor are characterized by increased sweating. They must take a bath or shower at least twice a day. If you do not keep your body clean, the moldy skin in the armpits becomes irritated and breaks out in rashes.
2. Shaving. Due to careless shaving, the skin of the armpits becomes irritated, covered with small scratches, and begins to itch. You need to shave only with a high-quality razor, and after the caring procedure, lubricate the skin with a softening cream.
3. Deodorants and antiperspirants. These skin care medications often clog the sebaceous and sweat glands. As a result, the skin becomes irritated, red, begins to ache and itch intensely.
4. Allergy. Armpit rashes are often the result of an allergic reaction to hygiene products. Allergens can be shaving foam, shower gels, and body lotions. Oddly enough, after shaving creams, which, it would seem, should soften and restore the skin, often become irritants.
5. Rubbing the skin with clothes. The skin under the arms is thin and delicate, it is easily irritated by tight and uncomfortable clothing. As a result, an itchy rash forms in the armpits.

The second type includes the factors described below.

• Candidiasis. Damage to the skin by yeast-like fungi. The carriers of the infection are people who do not follow hygiene rules. You can catch the fungus in public places: baths, solariums, swimming pools. The infected armpit turns red, becomes covered in a rash, and is very itchy. Candidiasis can quickly spread throughout the body, so it must be treated promptly.
• Eczema. Chronic non-infectious skin pathology of an inflammatory nature, manifested by scaly rashes. Diseased skin is tightened, covered with ulcers, blisters, scaly formations, and itches intensely.
• Psoriasis. Chronic non-infectious dermatosis, accompanied by the appearance of severely itchy and flaky crusts on the body.
• Furunculosis. Inflammation of the hair follicle with the formation of a purulent core. The disease is caused by Staphylococcus aureus, less commonly streptococci. Several boils may appear on the body at the same time.

Factors causing rashes in children

Most often, a rash in the armpits in infants is a consequence of miliaria - skin irritation due to excessive sweating and slow evaporation of sweat. The child develops pink or deep red rashes on his body, consisting of small bubbles.

Rashes dot the skin not only under the armpits, but in the groin area, on the chest, on the inside of the elbows and knees, and behind the ears. Miliaria usually appears during the hot season of the year if the baby overheats.

At the initial stage, irritation affects only the outer layers of the skin, so the child does not experience any discomfort.

When infected, the blisters fill with yellow liquid, grow, rupture, leaving behind quite large wounds. As a result, a severe purulent skin disease may develop - streptoderma, which requires complex therapy.

Therefore, prickly heat in a child should not be treated negligently. Parents should carefully monitor the cleanliness of the baby's body.

Irritated areas of the skin should be washed regularly with slightly warm water and blotted with a towel. Then the child should be left naked to take air baths.

In addition to prickly heat, armpit rashes in babies can be caused by the following factors:

1. Candidiasis;
2. Food allergies;
3. Contact dermatitis;
4. Failure to comply with hygiene rules.

Hyperhidrosis

Secreted by a large number of sweat glands located in the armpits, the secretion, when mixed with lard, forms a protective shell of the epidermis. This sweat accumulates in the armpit fold and in a short time begins to smell unpleasant. It produces a large number of bacteria.

In people with excessive sweating, secretion accumulates very quickly, and this does not depend on the mental state and physical activity. As a result, your armpits are constantly wet and smell unpleasant. The most important thing is that multiplying microbes lead to inflammation of the hair follicles and sweat ducts, and, as a result, the appearance of pimples.

Diagnostic measures

Medical diagnosis of armpit rashes can reveal the following diseases:

• Staphylococcus aureus. If a lump has formed under the armpit, then we can say that the rash is caused by Staphylococcus aureus. This disease negatively affects the entire body. Typically, the examination reveals such manifestations as elevated body temperature, malaise, feverish state, and inflammatory process. Usually the rashes are purulent in nature. After 10 days from the onset of infection, the seal opens on its own. After the diagnosis is made, treatment is prescribed, after which it becomes much better. The disease may recur after some time.
• Psoriasis. This disease manifests itself as redness under the arms. The color of the spots is uneven. The skin is thick, itchy, flaky.
• The fungus often causes discomfort on the skin. It can be picked up in public places. It can be contagious and is often treated with antibiotics. If the fungus is not treated, it will begin to affect other areas of the skin.
• Furunculosis. The rashes are purulent in nature and bring a lot of pain and discomfort. The disease can only be treated under the supervision of a specialist, as blood poisoning can occur. As soon as surgery occurs, as a result of which the boil is opened and cleaned, the patient’s condition improves significantly.

Diagnostics

First of all, one of the most effective and popular methods is an external inspection of the damaged area. During the visual identification of certain above-mentioned signs, diagnosis practically comes down to one option.

Also of great importance is palpation of the pathological growth to determine the size, consistency and temperature of the lesion.

But examination and palpation are sometimes insufficient measures to establish an accurate diagnosis: at the moment, specialists conduct a general blood test. A biological fluid must be collected for bacteriological diagnosis of the causative agent of the disease.

Treatment of this phenomenon, like other diseases, includes several interrelated elements. To cure the disease, it is necessary to use a combination of drug treatment and traditional medicine. The use of surgical intervention is used in exceptional situations.

Drug treatment

Medicines will help cope with discomfort, eliminate rashes, soothe and restore the epidermis. First you need to identify the cause that caused the rash.

Before using any topical product (gel, cream, ointment), it is necessary to clean the armpits of dirt and accumulated sweat. Any hypoallergenic products for sensitive skin are suitable for this.

You can also use a saline solution to cleanse the skin. You need to dilute 1 tbsp. a spoonful of salt in 0.5 liters of warm water.

For severe rashes and skin lesions, the following are suitable:

1. Cortisone ointments – “Dermatop”, “Fluvet”, “Ultralan”;
2. Gels and ointments with zinc oxide - “Desitin”, “Diaderm”, “Tsindol”.

Vaseline does not help cope with papules, but it perfectly helps relieve irritation and restore the skin. Fatty ointments and creams should be used with caution if there is hair on the armpits. Such drugs clog the follicles, contributing to the appearance of ulcers and the further development of inflammation.

If the unpleasant symptoms are caused by hyperhidrosis, then Botox injections for the armpits and laser liposuction are prescribed. For an additional therapeutic effect, vitamin and mineral complexes and a diet with limited carbohydrates in the diet are prescribed.

Some of the creams, such as hydrocortisone, Benadryl, Calamine lotion, are good for soothing the skin after mild irritation (itching, discomfort or pain).

Post-depilatory pseudofolliculitis

Women prefer to use more extreme methods to remove armpit hair:

• sugaring;
• waxing;
• electric epilator;
• tweezers.

When a hair is pulled out by its roots, the hair follicle is injured. As a result, the hair that appears later grows weak, it is not able to break through to the surface, so it bends and grows inward. At the place where it grows, the inflammatory process begins. This inflammation on the surface of the skin appears as a red pimple with a white head.

Preventing armpit rashes

If irritation occurs, you should not scratch the affected area of ​​the skin, otherwise the pathological process may intensify.
If you are prone to allergic rashes, you should use cosmetics and care products with extreme caution. It is necessary to wear clothes that are comfortable and loose, do not cut under the arms, do not restrict movement, and are made from natural fabrics. You should not buy T-shirts, tops, or bras made of synthetic materials.

If, after the appearance of the rash, your body temperature rises, and your armpits become swollen and begin to hurt, then you should immediately go to a medical specialist.

Symptoms

In addition to pain, this disease also manifests itself:

• peeling of the skin;
• visible redness;
• burning;
• discomfort when moving your arms;
• inflammation.
