I've got a terrible case of Jock Itch on the inside of my left thigh. It's been there for a while but usually pretty mild because I would occasionally (and very successfully) treat it with Lamisil. Lamisil worked great at first (I didn't follow the instructions correctly and always prematurely stopped using it at the first sign of it clearing up), and now Lamisil doesn't work at all. Right now its really bad, very scaley with cracking and some bleeding. I'm afraid that I've used Lamisil incorrectly for so long that my fungus has learned to adapt to it. What can I do? What else is there? Any suggestions?
