I have a nail fungus that I've dealt with for nearly two years. I have had my doctor prescribe cream, I also took Lamisil (spelling?) I went to the dermatologist with my son yesterday, and he told me to file the side of my nail with the fungus all the way down, he said in order to get rid of the fungus that's in my nail, I have to get rid of that part of my nail. Is this true? I also think I have a fungus on one of my toenails. I dropped something extremely heavy on my foot about two years ago, and lost the nail, it grew back fine. But then about a year ago, my toe started hurting badly. And now my toenail is starting to come off again. I'm not sure that it's a fungus there, but have no idea why my toenail would start to come off again for no reason.
