I am suffering from a kind of ringworm type thing for the last 4 months. It started as a small round thing in buttocks but now it has already spread till my hips and thighs. I tried using Candid-B cream after being recommended by a local physician but it is not responding. The rings start as a small acne type afterwards it spreads into a big ring and the outer ring part is very itchy. What could be the issue and whom should I consult for further treatment. Is this a curable one ? I am having all these questions and feeling stressed. Please help me.
