I've had foot fungus for many years. It comes and then it goes. I use the drug store stuff, lotrimin or something, and it goes away. Then I don't do anything, it's fine and it comes back again.

Reinfection is common with foot fungus, also called athlete's foot or tinea pedis. Many people who have chronic problems with foot fungus, need to take steps to avoid reinfection.

One of the best over the counter medications is Lamisil cream. Start by using the cream twice a day for 2-4 weeks. Once it appears to have resolved, use the cream once a day for a week and then every other day for about a month. If your feet sweat a lot, use an antiperspirant spray, as moist environments are a great place for fungus to grow. Make sure you rotate your shoes and air them out between use. Consider replacing old shoes and switch out all your insoles. Buy new, cheap liners (they even have anti-fungal liners at the drug store) for your shoes. Or place an anti-fungal powder or spray in your shoes. Consider buying anti-fungal soap (or soaps with tea tree oil) to use daily to prevent recurrence.

Unfortunately, this may be an ongoing battle. Most people stop using medications once they notice the fungus is gone, and don't take the necessary steps to prevent it from coming back again.
