What is urticaria?

Uticaria, or hives, can appear on any part of the body. Irritating and itchy, they look like swollen red circles on the skin. In most cases, hives go away in a matter of days, but for some people, they can be a recurring problem.

Urticaria, also known as hives, are red, itchy, welts on the skin that are typically caused by an allergic reaction to food or medication. They typically do not cause any lasting effects, though they can be irritating.

Urticaria is the medical term for hives. Hives are a common skin condition. If you develop hives, your skin breaks out in a rash of red bumps, which may be itchy. Allergies are a major cause of hives. People who are allergic to certain medicines, insect stings and bites, pollen, and specific foods may develop hives when exposed to these triggers. There are many other potential triggers for hives. A dermatologist can recommend treatments and lifestyle changes that can help to control and prevent hives.
