My boyfriend has had ringworm for about 4 months now. It first was visible on his hairline by his scalp/neck. We got some Lamisil and it cleaned it up in a couple of weeks. It was gone for about 2 weeks and all of a sudden came back! He immediately started treating it again thinking that he may not have cured it up completely. It went away and he kept using the lamisil in that area just to make sure. Well, then after a couple more weeks, it came back on his back. This one was much worse because he didn't know it was there. He has been treating that one for quite some time. It's going away but because it got so bad you can still see a mark. Well now he has it again on his head. He washes all of his clothes, sheets, bedding, towels etc quite frequently. Is there any reason he just can't seem to get rid of it?! Is there anything he can do?!
