Can urticaria kill me? i've had rashes for 6 weeks, am i gonna die?

Hives don't kill: Hives are very itchy and appear unsightly, but do not lead to death. They can be a sign of allergy or if going on for over 4 weeks, may be related to an autoimmune urticaria. Either way, there is pretty good treatment options especially with antihistamines. If there is swelling that affects the throat or breathing difficulties, see your allergist right away.
