Urticaria hives, also called “hives” or “nettle rash,” are raised, red, itchy bumps that appear on the skin. They can last from a few minutes to several days. The length of time that urticaria hives last can vary from person to person and even from one episode to the next.
Duration of Urticaria Hives
Urticaria hives can last for a few minutes to several days. In general, hives can last up to 6 weeks, but it is possible for them to last longer. Hives may also come and go over several days or even weeks.
Causes of Urticaria Hives
Urticaria hives can be caused by an allergic reaction to a substance, such as food, pollen, or medication. Stress, extreme temperatures, and certain infections can also trigger hives. In some cases, the exact cause of hives is unknown.
Treatment for Urticaria Hives
Treatment for urticaria hives typically includes antihistamines, topical creams, or steroid injections. In some cases, avoiding triggers and stress-reduction techniques can help reduce the frequency and severity of hives. In severe cases, a doctor may prescribe a short course of oral steroids.
