The disease you have is called urticaria, which is a temporary erythema and edema reaction caused by vasodilation and plasma extravasation, and belongs to allergic disease. Clinically, pruritic wheal mainly disappears suddenly (the rash disappears within 24 hours), which is mostly related to food, drugs, infection, mosquito bites, environment and other factors.

Treatment: It should be separated from allergens. What you said has something to do with eating fish and chicken. You should avoid eating this kind of food again. If necessary, you can check allergens and exclude other allergic factors. Western medicine treatment: you can take the third generation antihistamines (Kairuitan, Sitamin, etc. ) during the day. These drugs have little effect on drowsiness and have little effect on daily life and work. Ketotifen can be used at night. These drugs can be taken for a period of time and gradually reduced. Traditional Chinese Medicine Treatment: If it belongs to spleen and stomach disorder, it can be treated with Chu Shi Ling Wei Decoction. In addition, mental factors are also very important, because urticaria has certain self-limitation, so you don't have to be too nervous mentally and you can work and live with peace of mind. I hope our suggestions can help you and you will recover soon.
