There are a handful of different fungal strains that can cause athlete’s foot, but they all present in one of two ways.
Who knows? You can pick it up anywhere because the fungus is everywhere! The fungal spores are ubiquitous and found in most indoor and outdoor dust. It’s in your carpet, your clothes, your shoes, your bed… EVERYWHERE!!! It is important to note that becoming infected with athlete’s foot has little to do with hygiene. It doesn’t matter how often you wash your feet, infection is more determined by genetic predisposition. Some people are susceptible to it and some are not. It is not uncommon to see a husband and wife situation where the husband has been battling athlete’s foot for years, while the wife has never had it. Clearly the wife is exposed to the fungus, but her genetic makeup is such that she can fend off the disease.
What preventative measures can I take to decrease my chances of developing athlete’s foot?
Athlete’s foot prefers to grow in a dark environment; therefore, going barefoot or wearing sandals can be beneficial. Nothing cures athlete’s foot like a weekend at the beach with your feet in the salt water, sand, and sunshine.
Athlete’s foot also likes a moist environment; therefore, wearing absorbent socks to keep the moisture away from your skin is beneficial. Socks made from synthetic materials are better at “wicking” moisture away from the skin. Stay away from cotton socks. Cotton is good at absorbing moisture, but it holds the moisture against your skin creating an environment conducive to fungal growth.
One final, and perhaps less elegant, home remedy is to urinate on your feet while in the shower. Yes, that’s right, I said to pee on your feet. Urine contains a chemical called urea which is found in some antifungal medications. Urea is a strong keratolytic which means it dissolves skin. The urea assists in removing the scaly dry skin caused by the fungus. Urine is sterile and “all natural,” so if you’re not too grossed out, give it a whizz (ha!).
Are any of the over-the-counter (OTC) athlete’s foot medications any good?
Yes, most athlete’s foot can be cured with OTC medications. There are many available including Desenex, Tineaside, and Lamisil cream. The creams are applied twice daily and the condition usually resolves in 2-3 weeks. We recommend continuing treatment for an additional week after the condition has resolved to prevent reoccurrence.
I’ve tried the home remedies and OTC medications, but I just can't get rid of this fungus. Now what?
If you are particularly susceptible to athlete’s foot or have been infected by a resistant strain, topical OTC medications may not be enough to kill the infection. If this occurs, it is time to see a podiatrist. For very resistant strains of fungus or very susceptible individuals, oral antifungals are available. Oral antifungals are typically used in conjunction with prescription-strength topical medications. Your podiatrist may also order blood work to rule out other underlying causes of the persistent infection.
