Urticaria is a common dermatological condition that occurs as a direct result of a variety of allergic factors. In clinical practice, urticaria is a localized tissue edema caused by increased vascular permeability after exposure to allergic factors. Among the common diseases of dermatology, urticaria is considered a very common disease, and patients must not have a psychological burden after the occurrence of urticaria. The majority of patients do not know the cause of the onset of urticaria, and the majority of patients have transient urticaria, which can be controlled after effective medication and no longer appear for a long time. However, if hives occur, you must go to a regular hospital dermatology department for treatment.
