HealthDay, March, 2008 by Diana Kohnle

(HealthDay News) - Hives are red, raised patches of skin that are usually very itchy. Hives themselves often are not serious, but they may indicate a more serious condition.

The U.S. National Library of Medicine lists these common triggers for hives:

Some medications. Foods that many people are allergic to, including shellfish, nuts, eggs and milk. Pollen. Dander from animals, notably cats. Bites from insects. Infections and some illnesses, including lupus and leukemia. Stress or anxiety. Prolonged exposure to the sun or the cold. Excessive sweating.
