In brief: Urticaria

Common triggers of hives (urticaria) include medications, foods, insect bites/stings or exposure to extreme weather. The cause of chronic urticaria is thought be related to a person's own immune system triggering the reaction.
Some chronic urticaria can worsen with increased blood flow due to exertion, stress, alcohol, or fever. May be associated with h.Pylori, hepatitis or hyperthyroidism.
