I have a few round, red circles which appear in the crease where my inner thighs meet my torso- on both sides (two on each). They aren't raised, they don't itch, don't seem dry, don't puss- or really exist at all except for in appearance. I researched STDs due to their location, but didn't find anything that really matches their description.
As I said, there are two on each side. The ones on my right side are larger- biggest being slightly less than half an inch across. The smallest on the left is about half a centimeter across. I have not seen anything on the rest of my body. They started to appear not long after I began a job which requires me to be on my feet and walk a lot. Could this have something to do with it? They don't feel like an irritation that I would assume would be associated with that.
I'm not sure if they have increased in size. I do think that their color changes (becomes darker and lighter).
Do you know what this could be?
