I've injured my toenails while I was exercising/running, now 4 of my toenails look like they have fungi. I have been applying over the counter medication for past 3 months directly on the toenails, but the fungus is not diminishing. I do not want to take Lamisil, because of it's potential damage to the liver. I have been soaking my feet in Listerine, because I've heard that it helps. Does anyone have any other recommendations?

PS. I keep my feet clean, fresh socks, new shoes, I try to keep my toenails open as much as possible, because fungi loves dark moist areas. So I am doing everything I can, I just do not see any improvement. Please HELP!!!!
