Hives must be all over the body.

Urticaria must be all over the body hair, in fact, this problem is not in medicine this kind of saying, there is no so-called hair out or hair out of this concept, and not let the patient's rash grow out after the good concept. The principle of treatment of urticaria is to let the wheal go down, not let it out. Therefore, there is no concept of whole body hair for urticaria, treatment according to standard treatment guidelines can be treated, the use of anti-allergic drugs. If long-term regular urticaria, that is, chronic urticaria can go to the hospital to do laboratory tests, such as detecting allergens, etc. But the so-called whole body hair or not hair this statement does not exist.
