An itchy red rash on the body of an adult. what it could be, photos with explanations, reasons, which doctor to see

A red rash on the body is an alarming sign that signals the presence of a certain disease. The condition of the skin can reveal a lot about the internal state of a person. Rashes on the body may indicate the presence of pathological abnormalities, infections and inflammations. In almost all cases, the reasons are not as harmless as they might seem.

Of course, there are situations when a small rash on the body does not pose any particular danger, but is a reaction to a certain irritant. To exclude the possibility of diseases, you need to seek help from a specialist and undergo an examination. Only a doctor can identify the exact cause of such a reaction and prescribe proper treatment, because a rash can be just one of the symptoms of a dangerous pathology.

Types of red rashes on the skin

A rash on the body of an adult may differ in shape, location, and color. It all depends on what formed the basis for such skin changes. It is not difficult for an experienced specialist to determine what was the result of the rash and what nature it has - infectious or non-infectious. During a visual examination, a more detailed diagnosis is prescribed, on the basis of which complex treatment is prescribed.

A rash on the body can be presented as:

These types of rashes on the body in most cases do not rise above the skin level. They can be of different shades: from pale pink to dark red, it all depends on the reasons for their appearance. In some cases, a small rash on the body of an adult may be localized in a small area or may cover almost the entire body. If such symptoms appear, you should immediately consult a dermatologist.

Blisters are usually small in size, but they can accumulate quite a lot in a small area of ​​the body. They are slightly rough to the touch and have a dense structure. They do not bring any unpleasant sensations, pain or discomfort, but this does not mean that such a symptom does not pose a threat.

Ulcers are presented in the form of inflammations filled with pus. In an adult, such a rash most often indicates the presence of serious diseases, but in adolescence, therefore, ordinary acne may appear. Experts call it a pustule.

The blisters, filled with clear liquid, have a small diameter and may rise slightly above the skin level. To have an accurate idea of ​​what caused the formation of small bubbles, it is necessary to undergo appropriate tests. If the skin rash is bright red and slightly raised, the person is dealing with erythema. In most cases it is localized on the cheeks, but can spread throughout the body.

Purpura is subcutaneous hemorrhages. These lesions are not raised and have a red tint. Enanthema is a rash that occurs on the mucous membranes. Quite often, nodules can form, which almost always rise above the skin and change shape and color. Any of the listed conditions requires immediate qualified intervention.

Let's look at the main types of performances

Spot – Manifested by a change in shade or redness of the skin. It occurs in diseases such as syphilitic roseola, vitiligo, dermatitis, and birthmarks and freckles are also included in this type of manifestation.

Blister - Located in the thickness of the skin, inside it is filled with hemorrhagic fluid, measuring from 2 to 6 mm, usually occurs with eczema, herpes, allergic dermatitis.

Blister - Swollen redness with smooth edges, can be of regular or irregular shape, common causes of appearance: urticaria, insect bites, toxicoderma, usually does not require special treatment.

Typical manifestations of the nodule are caused by: psoriasis, several types of lichen, eczema, papillomas, various warts.

Causes

Before starting treatment, it is important to identify the main provoking factor. A skin rash may be the cause of an allergic reaction to certain foods or medications, or it may also indicate internal abnormalities. You should not self-medicate, as this can significantly worsen the problem. A person cannot diagnose himself, as a result of which it is almost impossible to eradicate the problem on his own.

The most common causes of small red spots are allergies, infections and a reaction to a weakened immune system.

When the provoking factor is eliminated, the problem itself disappears. Therapeutic measures include not only relieving external symptoms, but also eliminating the problem from the inside. Strengthening the immune system also plays an important role.

Gradually, the color and size of the rash may change, and the initial manifestations are replaced by a secondary reaction. This is fraught with changes in the skin, the formation of scars.

If you do not pay attention to the red rashes, over time they will become covered with cracks and crusts , and during an exacerbation they will begin to peel and itch.

That is why it is important to move on to treatment in a timely manner, before the problem worsens and begins to cause serious inconvenience.

Causes of skin allergies

Among allergies, skin manifestations mainly include conditions such as atopic or contact dermatitis, urticaria. The causes of a reaction to an allergen are low-molecular substances.

These include:

1. Metals that come into direct contact with the skin. For example, such an allergen can be found in various industries.
2. Latex.
3. Medicines . Often, it occurs due to frequent abuse of any medicine. Can be found in children.
4. Cosmetical tools. This is especially true for cheap, low-quality products.
5. Household chemicals, cleaning products. For example, many modern people have an allergic reaction to chlorine and chlorine-containing cleaning products, this can be especially common among medical personnel.
6. Food . Consumption of citrus fruits, honey, nuts, dairy products.

Let's take a closer look at atopic dermatitis. It most often occurs in children under one year of age. Inflammatory processes occur in combination with swelling, and all this is accompanied by pain. The lesion begins from the cheeks, then the scalp is involved in the skin reaction and only then goes down to the shoulders. With repeated attacks of dermatitis, the skin reaction will descend lower, that is, to the bends of the elbows and knees, to various skin folds. Remember that all this is not only painful for the child, but also itchy.

Provoking factors

The causes of a rash on the body are most often hidden in a banal allergy. The first rashes appear literally a few hours after contact with the allergen. At the same time, they can be itchy, there is a burning sensation, and sometimes even pain.

In more serious cases, the itchy rash is the result of an infection, fungus, or syphilis. With this condition, the rash will always itch and hurt. With repeated syphilis, nodules and crusts form on the skin, which brings a lot of inconvenience and discomfort to life.

A bright red rash always indicates the presence of dangerous skin pathologies.

You need to start treatment as quickly as possible. Eliminating the problem in the early stages will help avoid the appearance of eczema, scabs, scars, and, in rare cases, loss of limbs.

Infectious causes of the disease

Most often, if the appearance of a rash is accompanied by extremely unpleasant sensations, a person is dealing with an infection. In most cases this could be:

One of the most dangerous infectious diseases is syphilis. Infection occurs through sexual contact. At the secondary stage, the red spots become bright and cover the entire body. Most often, they do not bring discomfort, and after a while they may completely disappear on their own. However, soon a small rash will appear on the back, under the mammary glands and in the groin area.

Ringworm is a fungal disease. Externally they can manifest themselves in different ways. Sometimes small pale spots may appear on the patient’s body, sometimes they become brown or resemble scales. This process is accompanied by peeling, itching and pain.

Warts form only on the hands and feet; these formations are hard and dense. Molluscum contagiosum is a small capsule that is completely filled with liquid. When pressed, it pours out, leaving a small red area on the skin. If we are talking about herpes, then it can only appear on the face. At first these are small light bubbles, which over time become cloudy, burst and leave behind small reddish crusts.

The most common fungal disease that affects the feet is rubrophytosis. The rash can mainly be seen between the fingers. In the absence of proper treatment, it spreads throughout the entire foot, begins to peel off, and a strong unpleasant odor emanates from the feet.

Genital warts are found in the genital area. At first they look more like warts, but over time they change and look more like a red rash. Pemphigus is localized on the back, in the form of a large cluster of vesicles (hence the name). After a few days, they burst, begin to change color and more closely resemble small scars, although they are not.

What is a papule?

You can find out what a papule is from a medical encyclopedia or the Internet. If a person has papules, there is no need to go through an educational program on the World Wide Web, it is better to go to a good dermatologist, establish the true cause of the rash and undergo the correct course of treatment.

Papules are pink, red, purple and brown.

Papulopustular rash

If a person has one pimple, then this is not a problem. If there are a lot of acne, then it is necessary to undergo a course of treatment, since the rash indicates a problem in the body.

A papulopustular rash can cause scarring on the skin. Severe acne is not very common, occurring in about 10% of people.

Pearly (pearly) papules

Pearly penile papules are small white nodules arranged in one or more rows around the penis. Pearly (pearly) papules are a cosmetic defect; they are not sexually transmitted. You cannot remove papules yourself, even if they bleed or itch.

Papules on the scrotum and base of the penis are Fordyce granules - sebaceous glands that protrude on the skin. There is no need to treat them, since this is a physiological feature of the genital organs of all men.

Pearly papules appear due to blockage of the sebaceous glands of the glans penis.

Non-infectious rash

Infection is not always the cause of the problem. There are diseases that can provoke the occurrence of various rashes. These include:

Lupus is a rheumatic disease. The spots are pink. Most often they can be seen on the neck, hands and face. The rash located on the bridge of the nose may visually resemble a butterfly; it does not itch. After some time, it becomes denser and rougher, and begins to peel off.

Dermatitis affects those areas that are prone to sweating and where the most sebaceous glands are located. The nature of the lesion is minor, the spots have a yellowish and pink tint. Over time, the skin peels off, cracks form, and the process is accompanied by itching and pain.

Adolescence is characterized by the formation of acne. Small pustules form on the face, neck, back and chest, and on other parts of the body they are extremely rare. The most dangerous cause of rash is melanoma, which is a skin cancer. A small brownish elevation forms on the skin, with red or pink spots.

Urticaria is also considered a serious illness. It most often appears as a result of allergies. Small red pimples spread all over the body, they itch, itch and hurt. Sometimes the temperature may rise.

Psoriasis brings a lot of inconvenience to a person. Papules have a bright red or pink color, and at first, these elements are small and isolated, but over time, they merge into a large plaque covered with scales. At the beginning, changes on the skin do not cause any unpleasant sensations, but later the rash on the body itches, burns and hurts. Unfortunately, it is impossible to get rid of psoriasis; the patient can only temporarily alleviate the condition and stop the formation of the rash.

One form of dermatitis is diaper rash, which is caused by heavy sweating. They are found in the groin area, armpits, and between the buttocks. Manifestations can be either very large or in the form of small red pimples that itch and hurt.

Types of rash

Modern science divides skin redness that causes itching into the following types:

An example of a rash on a child's hand

• Stains. The color of such a rash depends on the reasons for its appearance and can be white, red or brown. It can occupy a specific area of ​​the human body or spread throughout it completely.
• Blisters. Small, dense, rough formations that appear in small groups on skin areas.
• Pustule. Volumetric purulent elements of the rash, often appearing in adolescence.
• Bubbles. Flat volumetric formations of small size, filled with transparent liquid.
• Erythema. A voluminous area of ​​skin with a rich red color that appears on the face.
• Purpura. Bleeding under the skin and on its surface, which appears as reddish colored areas.
• Knots and knots. Volumetric skin formations that can change color and shape during development.

These types of rashes can appear on any part of a person’s skin: on the wrists, shins, thighs, pubis, ankles, knees and other areas. If a rash appears on the skin, which itches and causes discomfort, it is necessary to look for methods of treatment.

Therapeutic measures

If a rash appears on the body and does not go away after a few days, you need to contact a specialist who will conduct an initial examination. He will refer the patient for further diagnostics in order to identify the provoking factor. Only with this approach can the rash be properly treated. The most important thing is not to hesitate, such changes can cause the development of serious diseases.

If such changes are the result of an allergy, the first thing to do is to stop all contact with the allergen. Sometimes this is extremely difficult to do, because what exactly caused the reaction is often unknown.

A red rash can often occur after contact with dust, washing powders, various personal care products, or after taking certain antibiotics.

To eliminate the symptoms, you need to change cleaning products, regularly carry out wet cleaning, try not to eat large quantities of citrus fruits, sweets, spicy and salty foods. Along with this, it is necessary to take antihistamines.

Drug treatment

Depending on what resulted from such a reaction, one or another drug is prescribed. Only by eliminating the cause itself and curing a certain disease can the surface of the skin be restored.

Treatment of an allergic reaction is carried out with antihistamines and corticosteroids. The most inexpensive of them are Eden, Cetrin and Suprastin. It should be remembered that such drugs will not get rid of the allergy itself, but will only eliminate the symptoms and reduce the sensitivity of receptors to the allergen.

Non-hormonal ointments and sedatives will help relieve burning and itching. The affected areas should be treated with alcohol and brilliant green. If possible, you should not scratch the affected areas, because microbes can accumulate under the nails, which, if they get on the irritated area, can provoke even more itching and suppuration.

With constant scratching, an additional infection can form and small wounds may appear. They do not heal for a long time; fluid constantly oozes from them. In this case, you should contact a dermatologist and take appropriate scrapings from the wound. Only after this the doctor prescribes treatment. Typically, corticosteroids and antibiotics are prescribed for this. Most often these are Akriderm and Betaderm ointments.

Some people prefer to sprinkle baby powder on the affected areas. It is hypoallergenic and does not cause adverse reactions, but it helps dry out small pimples. The most effective corticosteroid drugs are Advantan and Lokoid. Among non-hormonal agents, Gistan, Desitin and Bepanten are distinguished. If the cause of the small red rash is not an allergy, first you need to cure the patient of the disease itself, and only then proceed to eliminate the symptoms with the help of corticosteroids and antihistamines.

Treatment of papules

Redness on the skin may be accompanied by inflammation and suppuration. Papules cause pain and lead to cosmetic defects that reduce self-esteem.

Papules should be treated by a dermatologist. A specialist will be able to rule out a serious disease and prescribe appropriate therapy.

The inflamed area can be lubricated with iodine solution several times a day. The main thing is not to overdo it, as you can burn the skin.

Twice a day you can lubricate the papules with Baziron, Zinerit, Skinoren or Differin.

In advanced cases, antibiotics can be used externally and internally. It is impossible to remove acne in one go; in any case, you will have to take a course.

In addition to treatment, you need to start eating right. Eliminate coffee, sweets and smoked foods from your diet.

Hygiene is of great importance. Cosmetics for problem skin should be selected with a dermatologist. Every day the skin should be treated with cleansing gel, tonic and cream. If the water coming from the tap in your apartment is of poor quality, it is better to wash your face from a bottle, preferably with mineral water.

Mantu papule

The Mantoux test is a test for the activity of a person’s anti-tuberculosis immunity. Tuberculin, which is obtained from destroyed tubercle bacilli, is injected into the skin. The immune system recognizes tuberculin and a Mantoux papule appears at the injection site.

Biorevitalization of papule

Biorevitalization is a transformation of the skin structure. Young skin is very different from aging skin. Elasticity, firmness, tone, color, texture, hydration - all this changes with age.

Biorevitalization is the latest method of skin regeneration. It is needed by those whose skin is dehydrated and has a lot of gravitational and facial wrinkles.

Biorevitalization of the papule is quick and painless. The main thing is to find a good salon and a competent cosmetologist you can trust.

ethnoscience

Traditional medicine can only be used as an additional treatment, because resorting to unconventional methods will not cure the rash. Before using any folk remedy, you must notify your doctor.

Black tea compresses will help get rid of skin rashes. An infusion of chamomile and sage will give a similar result. To prepare the medicine, you need to pour 1 teaspoon of any crushed herb with a glass of boiling water, and leave it for about an hour. The infusion is filtered and used for compresses.

If the rash is localized throughout the body, applying a lotion is inconvenient; it is best to relax in a warm bath with the addition of string and chamomile. To do this, pour 5 tablespoons of plants with 3 liters of boiling water and leave for 2 hours. After this, the infusion is filtered and added to a warm bath. Shilajit will help in solving the problem; it is diluted in water and applied to the affected areas. In addition, it is recommended to drink carrot juice daily throughout the treatment.
