See your doctor. There are systemic medications that you can take that will eliminate nail fungus. athletes foot is easier to treat using over the counter anti-fungal medications (athletes foot creams and powders). I too suggest that you treat your shower stall and bathroom floor with bleach to annihilate fungus that may be living in those places and provided you use a public pool to bring your own flip flops and not walk encircling a abundance on the tiled floors of the changing room and shower without them.

I, too, own this problem, Marie, and it hasn't been accessible. What I accomplish is use tincture of iodine to the nail bed. It may take some time, according to a season, to see above progress, however it does slowly work, and is bigger than taking those pills. I too rinse my toes with hydrogen perixide between applications. This data came from my cousin, a doctor. Great luck!!
