I have ringworm of the groin. I have been using candid-b ointment (not regularly) and it gave me relief. It is pretty much in control but the skin is still reddish brown and itches a little bit. Do I keep using candid-b regularly as in twice a day? Will that make my skin normal if I use the ointment for 2 weeks regularly twice a day. The ointment was effective. Do I need to take any medications taken through mouth?
