An itchy raised red rash that begins with a "herald patch" and spreads. It looks a little like ringworm, but does not respond to anti fungals. It affects most parts of your body, except hands, feet and face, for some reason. There is no known cure, and it is "self limiting", usually lasting only 6 to 8 weeks. Mine lasted over a year! Sometimes called "Christmas Tree Rash", because it usually spreads first along the ribs, in a tree pattern.
