Urticaria

Say: ur-tuh-KAIR-ee-uh

Urticaria is the fancy name for hives, those itchy, red bumps people get on their skin when they're allergic to something, like certain foods or medicines. Allergies are not the only reason someone might get hives. Some infections, hot or cold temperatures, or even stress can make those bumps appear. Your doctor can give you some medicine that can help stop all your scratching.
