I have had CFS for almost 20 years but I have just recently started developing rashes on my body. They kind of look and feel like a brush burn type rash but I haven't done anything to cause it. The first one appeared on my leg, was right in the fold behind my knee, was very painful, burning, itching, and scaly. That one went away and now I have one on the back side of my upper arm. It is painful and burning - no itching or scaling yet. Does this sound familiar to anyone?
