Hives, also called urticaria, are raised welts on the skin. They are usually red, pink or flesh-colored. Hives are itchy, and they can also sting, hurt or cause achiness.

Allergic reactions are the main causes of hives. Stress, infections, illness, sweating and excessive exposure to hot or cold temperatures can also cause hives.

Hives are common and will probably go away with time. Both children and adults can get hives. In serious cases, you may need medication or allergy shots.

What are the symptoms of hives?

Red welts on the skin are the main symptom of hives. Welts can be small and round, ring-shaped, or even as large as a dinner plate.

They can change shape and spread. Sometimes, hives disappear and reappear over the course of an outbreak.

How are hives treated?

In mild cases of hives, you may not need prescription treatment. You can seek temporary relief by:

  • Taking antihistamines
  • Avoiding irritating the area
  • Avoiding hot water
  • Taking a cool or lukewarm bath with colloidal oatmeal or baking soda

If you break out in hives, consider possible causes—stress, food or any other external cause. If you have chronic hives, or hives that do not go away, seek a healthcare provider.

When to call 911

If hives are making it difficult to breathe or break out around your throat or tongue, or if larger welts develop under the skin, seek emergency care immediately by dialing 911.
