Last year I got rash under my leg above my right knee. It is bumpy, dry and very itchy. It starts off under right leg, then to stomach, then under left leg, to under arm and finally nose (not severe). That first time it went on for many months then went away. A few weeks ago it started all over again in the same order but each duration is less time than the first. I have to take burning hot showers to relieve the itching. Anyone ever hear of this?
