Last one has a darkened version to show the difference between the "regular" skin and whatever this is.
This is only on my right ankle, the left is fine. It doesn't hurt, burn, or itch. It doesn't feel rough, but the texture is somewhat different than the unaffected skin. I looked around online and saw pictures of "granuloma annulare" that looked similar when on the ankles, but I wanted to make sure it isn't something worse. The obvious worry would be diabetes, since I know people always talk about troubles with the feet when that occurs.
I thought I had noticed a red spot there before but I just happened to notice the dark spot there. After investigating a little further it had me worried. Maybe some of you will have an idea?
