Adults with papular urticaria usually need 15-20 days to be completely cured. Papular urticaria itself is also called insect bite dermatitis and is related to many factors such as mosquito bites, allergies, and irritation. When the body is exposed to mosquito venom or allergic substances, the local skin surface will show red maculopapular-like changes, accompanied by significant itching, some people will appear burning symptoms. And after scratching if there is a breakout, local pain can occur. The itching sensation will subside within 2-3 days after the regular medication, and the medication needs to be applied consistently. The raised papule-like changes will disappear only after comprehensive treatment. It is recommended to eat less irritating foods such as chili and seafood until the rash has completely subsided to avoid aggravating the itching of papular urticaria and thus affecting the therapeutic effect.
