The appearance of fluid-filled blisters on the skin can indicate both a simple problem and a serious illness. The rash is localized in different parts of the body, including the mucous membrane. It comes in different shapes and sizes. Next, consider when you should be afraid of blisters, and when not.
Symptoms and causes of a rash
In case of violations in the body, it signals this through the skin, which is manifested by dryness, a change in color or the formation of a rash. Rashes are in the form of spots, abscesses, vesicles and nodules. In medicine, the common name for such symptoms is exanthema. Bubble rash (vesicles) is easy to distinguish: a small tubercle appears above the surface of the skin, which contains a clear, or purulent serous fluid, which is characteristic of pustules.
Such formations can be the result of both mechanical damage to the skin, and infections and autoimmune diseases. Pemphigus is one of the dangerous causes of a rash that requires treatment. This is a rare autoimmune disease in which the rash occupies large areas of the body, including on the mucous membrane. The rash can be flaky, individual vesicles of different sizes merge into a single area. With such symptoms, the patient urgently needs hospitalization. Similar symptoms can occur with psoriasis. Although in this case the patient is not in danger, you need to contact a dermatologist to make sure the diagnosis.
There are more serious diseases in which vesicles also appear on the skin. Another autoimmune disease with a blistering rash is bullous pemphigoid. Appears only in older people. Vesicles cover only the skin, red spots appear between the pimples, the exanthema is compacted to the touch. If the rash is accompanied by symptoms of an eating disorder (bloating, vomiting, diarrhea, etc.), it may be dermatitis herpetiformis. In this case, the rash begins with the elbows and knees, buttocks, and the back of the head.
In addition to the main symptom of bubble exanthema, there are a number of accompanying symptoms. It can be fever, itching, lack of appetite. This set of symptoms is determined by the very reason why the rash appeared. The most common causes of rashes in the form of bubbles on the body:
- Prickly heat is a painful skin condition in which many vesicles appear in closed areas of the body and skin folds. The disease manifests itself after overheating, friction and sweating. With prickly heat, the rash is localized under the breast, in the gluteal cavity, in the inguinal folds. In children, this disease manifests itself in different parts of the body. Without treatment and prevention, vesicles suppurate.
- Infections. Vesicles often appear with chicken pox, rubella, scarlet fever, measles. If, along with the rash, the temperature rises, the lymph nodes increase, the tonsils become inflamed – the cause is most likely an infection. Avoid scratching the vesicles, as they may leave scars after healing.
- Herpes is a viral disease that differs from the rest in the place of rashes. Most often, with herpes, rashes in the form of vesicles appear on the lips, in the nasolabial folds, less often on the genitals. One or more vesicles filled with a clear liquid form on the body, a red rim appears around the tubercle. The rash in the early stages is itchy, hot to the touch. Such symptoms heal within a week without leaving marks. Bubbles on the mucous membranes and genitals should be treated with a specialist.
- Stomatitis – the appearance of vesicles in the mouth. It can also be accompanied by fever, lethargy, inflammation and swollen lymph nodes.
- Scabies is a disease caused by a mite. The causative agent is transmitted through household and sexual contacts, in natural conditions. Small bubbles appear between the fingers, on the palms, genitals. The appearance of vesicles is preceded by a rash in the form of spots, on the site of which tubercles with liquid are gradually formed, which are easily infected with mechanical irritation. Treatment takes place only under the supervision of a dermatologist.
- Allergies and insect bites are the most common and less dangerous cause of a blistering rash. In this case, vesicles can appear in any part of the body, sometimes they unite and occupy a large surface of the skin. A distinctive feature of such vesicles is severe itching, which causes discomfort and affects overall well-being. In allergy sufferers, the symptoms disappear after taking antihistamines. Insect bites must be treated with antiseptics, alcohol or iodine.
In addition to these causes, a vesicular rash appears from scratches and bites from cats. This is called felinosis, when when a person’s skin is damaged, the animal infects the wound. The first signs appear after 2 weeks, a seal with a red tint is noticeable at the site of damage. Then a vesicle is formed in the same area, lymph nodes increase, and the temperature rises.
