Urticaria is the medical term for hives and nettle rash. It is a condition characterized by the appearance of intensely itching welts or weals, usually with a raised centre and surrounding red skin. They appear in the area where an irritant may have come into contact with the skin or in crops, widely distributed over the body surface if the reaction is created by the ingestion or injection of a toxin. Urticaria generally disappears within a day or two.
