I have this mole on my upper left leg, near my crotch. It appeared maybe 5 yrs ago. It was all dark brown, but has gotten lighter with an almost purplish tint with a spot that is even lighter. I do not have health insurance and don't know what to do.
Since you have had this condition for so long and you don't have insurance, please go to the ER so you can be treated for this. From the look of the picture, it may be a fungus or certainly inflammation of that area. You need to have it treated as soon as possible.
