This weak membrane easily and rapidly breaks down under physical pressure causing an allergic-like reaction, generally a red wheal (welt) to appear on the skin. It can often be confused with an allergic reaction to the object causing a scratch, when in fact it is the act of being scratched that causes a wheal to appear. These wheals are a subset of urticaria (hives) that appear within minutes, accompanied by a sensation of burning, and itchiness. The first outbreak of urticaria can lead to others on body parts not directly stimulated, scraped or scratched. In a normal case the swelling will reduce itself with no treatment within 15-30 minutes, but in extreme cases, itchy red wheals may last anywhere from a few hours to days.
