Information for Patients


Also called: Urticaria

Hives are red and sometimes itchy bumps on your skin. An allergic reaction to a drug or food usually causes them. Allergic reactions cause your body to release chemicals that can make your skin swell up in hives. People who have other allergies are more likely to get hives than other people. Other causes include infections and stress.

Hives are very common. They usually go away on their own, but if you have a serious case, you might need medicine or a shot. In rare cases, hives can cause a dangerous swelling in your airways, making it hard to breathe - which is a medical emergency.

Vibratory urticaria Vibratory urticaria is a condition in which exposing the skin to vibration, repetitive stretching, or friction results in allergy symptoms such as hives (urticaria), swelling (angioedema), redness (erythema), and itching (pruritus) in the affected area. The reaction can be brought on by towel drying, hand clapping, running, a bumpy ride in a vehicle, or other repetitive stimulation. Headaches, fatigue, faintness, blurry vision, a metallic taste in the mouth, facial flushing, and more widespread swelling (especially of the face) can also occur during these episodes, especially if the stimulation is extreme or prolonged. The reaction occurs within a few minutes of the stimulation and generally lasts up to an hour. Affected individuals can have several episodes per day.
