I have a small round red circle on my upper thigh that I'm thinking is ringworm so I've been treating it for the past 3 or 4 days with Miconazole Nitrate. Last night when I got in the shower I noticed it has gotten bigger, about the size of a dime to nickel but now also has a puffy, swollen ring only on the outside of the rash. It hasn't been itchy until last night, now it's becoming itchy with a slight burn feeling to it. I'm thinking maybe I'm having a reaction to the antifungal cream I'm applying? Any opinion would be greatly appreciated! Thanks.
