Hives â also known as urticaria (ur-tih-KAR-e-uh) â is a skin reaction that causes itchy welts, which can range in size from small spots to large blotches several inches in diameter. Hives can be triggered by exposure to certain foods, medications or other substances.
This is especially true if your hives outbreak is accompanied by a fever, swelling in the throat, wheezing, or shortness of breath. In fact, around 33% of hives suffers can also have swelling of the tongue and throat, which is known as angioedema, and is caused by swelling beneath the skin instead of on the surface.
