Had athlete feet for 5 years now... how can i cure it?

Doctor can examine: Athlete's foot is a fungus infection of the skin. The fungus is somewhat contagious, but it is hard to tell how much contact one must have with the fungus before one develops a rash. If the rash spreads to the toenails, the fungus will be much harder to get rid of. To treat the skin rash, people use Lotrimin AF (clotrimazole), an over-the-counter cream that is inexpensive and sold everywhere.
