Hello sir, actually i have too many ringworms around my anus. They lie from the sides of my penis to the midways upto end butt line towards back. There are white patches.. these are dry. Some are red. I applied two creams itch guard and ring guard. But not totaal cured. I was not regular although. Now i am usin a cream containing benzoic and salicylic acid. Is this ok? Or should i do something else. Please suggest.
