I have this dark spot on my middle toe on my right foot. It occurred i believe due to a door sort of passing over my foot and kind of pinched the skin. I remember it looking bad but afterwards i thought it was blood that never got cleaned up under my skin. It has been there for about a year now from what I know and it does not heal! Since it is darker than my skin tone, it is noticeable and it makes me feel just the tiniest bit self conscious. I would like to be able to identify and treat it with the help of one of you!
