About a year ago I noticed like 2 small bumps on the inner part of my left forearm. Now a year later it's a whole cluster of them in one are. Now it seems like more are spreading within the same area. Out of curiosity it will scratch it and the area puffs up. The bumps doesn't itch at all. I do have highly sensitive skin, sweat a lot, and do have tinea versicolor.
No health issues, no unexplained weight loss, no swelling, no discomfort.....what are these spots?
