Dear Doctor, I think I am suffering from a severe case of groin itch. The skin around the area has turned black. I drive my own cab the entire day & at times the itching becomes severe, especially at night while sleeping. I have applied Clotrimazole Cream IP & I do get some relief but it keeps coming back. Usually during severe itching, I feel small lumps which itch the most! It is really embarrassing especially when am with clients sitting in my cab, Please Help!
