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.
Cold urticaria (essentially meaning cold hives) is a disorder where hives or large red welts form on the skin after exposure to a cold stimulus. The welts are usually itchy and often the hands and feet will become itchy and swollen as well. Hives vary in size from about 7mm in diameter to as big as about 27mm diameter or larger.
