Common skin conditions

Hives (urticaria)

Hives are raised, itchy welts that appear and fade, often within hours. They can be triggered by foods, medicines, infections, heat, pressure or stress, though often no single cause is found.

Common signs

Raised pink or red welts
Welts that change shape or move around
Itching or burning
Swelling of lips or eyelids (angioedema)

How it is treated

Treatment usually starts with identifying triggers and taking antihistamines. Hives lasting more than six weeks (chronic urticaria) may need additional prescription treatment.

When to see a dermatologist

Seek emergency care right away for hives with trouble breathing, throat tightness or swelling of the tongue. See a dermatologist if hives keep returning.
