How to cure urticaria completely

Urticaria is divided into acute urticaria and chronic urticaria. Acute urticaria has a prolonged course and will turn into chronic urticaria after more than six weeks. Because acute urticaria is a type I allergy, the onset is acute and the condition is relatively fast. If a clear allergen is found, most of the allergens can be self-healed after removal. Some acute urticaria are caused by infectious factors and are called infectious urticaria. This is generally not self-healing. Chronic urticaria because the etiology is more complex, normal is unable to clearly find allergens, treatment can use antihistamine drugs to control the symptoms of urticaria, but can not achieve a complete cure. Chronic urticaria has a part of patients, its course is self-limiting, that is, after some years of treatment, sometimes in the absence of treatment, also cured by themselves, this is determined by the course of self-limiting, is a certain self-healing rather than a complete cure.
