Hives (Urticaria) Allergy
Urticaria is the term for hives in medicine. One common indicator of an allergic reaction is hives. Viral infections are among the other possible causes of hives.
Raised spots on the skin known as welts or wheals are known as hives. Hives can appear anywhere on the body and can be tiny or huge. The hives itch. An acute allergic reaction to an allergen may result in hives. It is possible for hives to be only one of several symptoms of an allergic reaction. Anaphylaxis, a severe allergic reaction that causes hives, is pronounced "anna-fih-LACK-sis."
There are unknown causes of hives. These kinds of hives are referred to as idiopathic urticaria. The term "unknown cause" is idiopathic. Chronic hives are also possible. Your doctor may identify chronic spontaneous urticaria, or CSU, if you have persistent hives for no apparent cause. Before, it was known as chronic idiopathic urticaria (CIU).
