Dr gave me an antifungal cream for a groin rash I developed during last month and a pill to take once a day. However, the rash has not gone away and now I have several black heads developing in the area that are cream or white in color and stand out. No pus secretes from these nor can they be popped. Does anyone know what kind of rash this is? It doesn't have the typical red patch of Jock Itch. %-)
