Anyway, about a month ago, my underarms started to itch again, and I discovered a small, hard, brown-gray patch near the front of my underarm. It looked and felt like a bumpy scab, but it wouldn't peel off and never went away, and is painful when I tried to pull it off like a scab, however, it didn't bleed or look like a wound when I did. It looked like it was attached to/part of my skin.
