What's wrong with the red patches on the skin

Many people have encountered red patches, but most people don't pay much attention to them. If you want to know what the red patches on your skin are, you must understand it from many aspects. It may be a simple red patch, or it may be related to some skin diseases. For example, urticaria.

1. Erythema is not uncommon in dermatology. Generally, the onset is rapid, and the clinical manifestations are symmetrical appearance of erythema, papules, wheals, blisters, bullae and purpura on the body, and they mostly occur on the extensor side of the limbs. Target lesions or iris-like lesions are typical manifestations of this disease, which are mostly seen in the hands and feet. They look like round edematous erythema with blisters in the center. According to current research, this disease is a cell-mediated immune response. It is recommended not to use drugs on your own, but to go to the hospital's dermatology department for review and treatment under the correct guidance of a doctor, so as not to delay the disease.

2. It may be urticaria, also known as hives. It is recommended to choose cetirizine hydrochloride drops or loratadine for treatment. During the treatment, be careful to avoid inhaling pollen, dust, etc., eat more fresh fruits and vegetables, and eat less fried, deep-fried or spicy foods that are more likely to induce thermal reactions in the body.

3. It is very likely to be tinea versicolor, which is mainly caused by infection with Pityrosporum. It is usually easy to recur the next year after treatment. Antifungal treatment is the main treatment. Go to a regular hospital dermatology department for treatment. After diagnosis, actively treat under the guidance of a doctor. Do not scratch, reduce sweating, and pay attention to hygiene.

4. It is not ruled out that the clinical symptoms are caused by allergies. It is recommended to use drugs such as loratadine hydrochloride in time to improve the clinical symptoms caused by allergies. When necessary, visit a dermatologist to check the cause of the allergy, treat the cause, improve the condition, and use vitamin C in conjunction with treatment when necessary.
