Service Directory Links Hives , or wheals , are raised red itchy bumps that develop on the skin.
Hives can occur almost anywhere on the body.
Dial 911 or have someone take you to the emergency department immediately. In most cases hives are irritating, but harmless. Hives almost always clear within 2 - 24 hours without treatment. Calamine lotion or other anti-itch lotions or creams may be applied to the skin to reduce the itching. In some cases antihistamines are required to help clear the hives and reduce the itching.
