What is Hives?
How is Hives diagnosed?
Hives are raised red bumps (welts) or splotches on the skin. They’re a type of swelling on the surface of your skin and happen when your body has an allergic reaction. Allergic reactions happen when your immune system comes in contact with an allergen. Allergens are proteins that are harmless to many people but cause an allergic reaction in sensitive people.
Our doctors can diagnose hives and angioedema by looking at your skin. Allergy tests can help identify what’s triggering a reaction, but this is true primarily for acute hives.

Hives can last a variable amount of time. Usually, eruptions may last for a few minutes, sometimes several hours, and even several weeks to months. Most individual hives last no more than 24 hours.
When should I be worried about hives?
Seek emergency medical care. Chronic hives do not put you at sudden risk of a serious allergic reaction (anaphylaxis). If you get hives as part of a severe allergic reaction, seek emergency care. Symptoms of anaphylaxis include dizziness, trouble breathing, and swelling of the tongue, lips, mouth or throat.
