Allergic dermatitis is essentially a skin disease caused by immune dysfunction in the human body. The occurrence of allergic dermatitis requires two conditions, namely, allergic constitution and the presence of allergens. Dermatologists point out that the symptoms of atopic dermatitis vary depending on the type of atopic dermatitis. And the symptoms vary at different stages. The symptoms of allergic dermatitis are complex and require careful investigation and symptomatic treatment. The following are some symptoms of allergic dermatitis:

1. Drug rash Some drugs can cause skin allergic reactions, which are mainly manifested by skin erythema, purpura, blisters, epidermal relaxation, itching and pain. Sometimes they are accompanied by low fever. After the rash subsides, there is usually no pigmentation. Western medicine allergies are more common, such as penicillin sulfonamides (such as SMZ) and analgin allergies. Some ingredients in traditional Chinese medicine can also be allergens.

2. Contact dermatitis refers to the local occurrence of erythema, edema, itching and pain after the skin comes into contact with a certain substance. In severe cases, blisters and peeling may occur. Substances that can cause contact dermatitis include jewelry, watch chains, glasses frames, sandals, chemical fiber fabrics, topical medicines, chemicals, cosmetics, etc. Once the above symptoms are found, immediately look for the items that cause allergies and stop contacting them. People who are prone to contact dermatitis are mostly allergic people.

3. Eczema has obvious exudation. The incidence of eczema has been on the rise in recent years. This is related to the abuse of chemical products, environmental pollution, poor waste management, accelerated pace of life, increased mental stress and other factors. Characteristics of the disease: A. It can occur at any age; B. It can occur at any part of the body surface; C. Repeated attacks; D. Erythema, papules, blisters, erosion, exudation, scabs, desquamation, and pigmentation can be seen locally or throughout the body;
