I have a ringworm problem since 6-7months and that is mostly around my waist, private part, underarms, under and around my breast. I had visited the dermatologist and he prescribed some medicine however sometimes it goes away but the area becomes very itchy and I keep on scratching and gets black big spots there, after 3-4 days new ringworms comes. I don't know the root cause of the same. I need the permanent solution to this and want the solution to get rid of those awful marks. Please help me.
