Hi, Something that works well on toenail or fingernail fungus is plain old Vicks Vapor Rub. Trim the nails and then apply two times daily. When the nails grow out the fungus is gone. I have personally seen this work 9-10 times with no side effects. My internal medicine doctor also told me that he could think of know reason this would be contraindicated for diabetics. I read about this in the newspaper in the "Ask Dr. Gott" column and it does work. Paula:nurse:
