hi this is a visual thing you should really get your doctor to look for you i think you find this is best advice. good luck
my husband found a dark lumpy patch on the interior of my buttocks. it doesn't itch or burn. what could this be? . the area doesn't have any noticeable discoloration or raised skin in the surrounding area. it's localized and appears to be greyish black in color - looks a little fuzzy but my husband said there's no hair. i wouldn't even know it's there unless he told me but it concerns me as it wasn't there before.
