Have developed dry skin near the groin area and now it is spreading. skin there has gone blackish greyish and becomes extremely dry. it itches as well as sometimes will get blisters and starts paining. recently. it has started to show up on one of the knee area. Am very shy to go to a doctor with this condition. could you please suggest a male skin specialist or something that i can do to cure my problem. Thank-you for your help.
