Itching Swelling of the surface of the skin into red- or skin-colored welts (called wheals) with clearly defined edges.
The hives may get bigger, spread, and join together to form larger areas of flat, raised skin.
They can also change shape, disappear, and reappear within minutes or hours. A true hive comes and goes. When you press the center of one, it turns white. This is called blanching.
