It was not there two days ago, I know for a fact, it just appeared, I noticed it when I pulled off my shirt and just felt it. It's not black and it does not hurt. About the size of a small pencil eraser. I am a year away from 50 and I have been told the older you get the grosser you get so maybe its just a skin tag or something. No I am not pulling a cmoney fake spot here, but I am concerned this just happened. Really don't need this stress right now.
