Hives, called urticaria by the medical profession, is a skin condition that is characterized by sudden outbreaks of red, itchy welts on the skin. Any area of the body may be affected. The welts may vary in appearance, from tiny, goose ‘bump-like spots to rashes that cover significant areas of the body. Hives usually go away within a few hours to two days, but in rare cases they become chronic and may last for six weeks or more. Hives are an allergic reaction. Unfortunately reaction can be anything, including cold, heat, and even emotional tension. Unless you already have a good idea what is causing hives or if a new drug had just been taken, the doctor is unlikely to be able to determine the cause. Most often, a search for a cause is fruitless. Hives are raised, red, itchy, often fluid-filled patches of skin that may appear and disappear at random. They range in size from less than 0.6 to 2.5 cm (0.25 to 1 inch) or more, and they may last a few minutes or a few days. A single hive commonly develops after an insect sting. Multiple hives often develop in response to a drug, food, or infection. Most people have only one attack of hives lasting form a period of minutes to weeks.
