About Hives. Hives (or urticaria) are red raised bumps or welts on the skin. They can appear anywhere on the body and can look like tiny little spots or large interconnected bumps. Individual hives can last anywhere from a few hours to a week (sometimes longer), and new ones might replace those that fade.
Welts are very often seen in the form of hives, itchy red swellings due to an allergic reaction, says MedlinePlus. They result from histamine and other chemicals being released into the blood and may be triggered by bug bites, particular foods, environmental allergens or medicines.
