DEAR DOCTOR K: I have athlete's foot. How can I get rid of it? And how can I make sure I don't get it again?
DEAR READER: Athlete's foot is a common fungal infection. It got its name because walking around barefoot in a locker room is a good way to become infected. You can also pick up the fungus from improperly cleaned instruments used in a pedicure, in the dressing rooms of clothing stores, in swimming pool changing areas, or anyplace that combines dampness and a lot of foot traffic.
