Q: Before my wedding, before job interviews, and anytime I have a bit of stress, my arms, wrists, and hands break out in an itchy rash. Can stress cause a rash? How do I prevent this from occurring, and how do I treat it?
A: Stress is one of the known triggers of hives, an outbreak of raised, red spots (or welts) on the skin that often itch. Hives are usually indicative of an allergic reaction, but they can also occur as a result of sun or cold exposure, infections, excessive perspiration, and emotional stress. It is not known exactly why stress may precipitate an outbreak of hives, but it is likely related to the known effects of stress on the immune system. The medical term for hives is urticaria.
