I am suffering Itching problems in groin and butt region for almost a year now. I have tried basic anti fungal cream and powder but they are of very less use as Itching use to come back. I even tried itaspor 100 mg and Onabet cream but after I stop using the problem use to come back again and again. It itches too much and also creates a black stain. Itching increases during night. What should I do to cure it permanently?
