The rash or bumps started on the inside of my upper arm several years ago. Between arm pit and elbow. Started small and then grew to a line like rash that was just in that one spot. Last year I noticed that I was getting what looked like little bruises on the top of my foot and on my calf and knee, then on my elbows and a little spot on my back. I noticed that they eventually turned into the little rash that looked similar to what was under my arm. Most times circular but sometimes like under my arm which is a line (mostly). The rash under my arm is getting more pronounced and noticeable. The others that have shown up are still faint and not very noticeable. A new spot will show up maybe once every 3-6 months and then will progress very slowly. Under arm is still the worst spot. ???? Sorry forgot to say it does not itch at all.
