What are the symptoms of contact dermatitis
summary
I have just suffered from contact dermatitis. The characteristics of this skin disease are very obvious. It can form erythema, swelling and papules on the skin, but it needs to be distinguished from other diseases. Let's take a look at the symptoms of contact dermatitis.
What are the symptoms of contact dermatitis
Symptom 1: distribution of lesions. Skin lesions are often distributed in the contact area, with a certain shape and clear boundary, and are related to the contact mode of the pathogen. According to the location of the disease, the possible cause of the disease can be found. For example, allergic reactions to cosmetics and hair dyes are often considered for head and face contact dermatitis, and the skin lesions caused by allergic reactions to underwear dyes can be distributed in the shape of pants.
Symptom 2: characteristics of skin lesions. Erythema, papule and herpes with clear boundary, and obvious redness and swelling with blisters or bullae in severe cases. The blister wall is tense and the content is clear. After the blister is broken, it is erosive surface. In severe cases (such as strong acid and strong alkali), the epidermis may be peeled off or even necrotic. In the skin tissue is loose, such as the face, scrotum and other places often have obvious swelling.
Symptom 3: the course of disease is self limited. The symptoms of dermatitis develop to the peak within a few days. If the patient has been out of contact with the pathogen, it can gradually subside within 1-2 weeks, leaving temporary pigmentation. A few patients in the process of repeated contact, the sensitivity of contact material gradually decreased or tolerance improved, desensitization tolerance state occurred and improved or recovered.
matters needing attention
Contact dermatitis patients with the best diet is light, can eat less food that is easy to cause allergies, such as wine, seafood, and can eat more fresh fruits and vegetables, to provide adequate nutrients for the body.
