Skin fungal infections are frequent among men who may acquire these infections through walking around barefoot at the gym or pool. When the feet are affected, “athlete’s foot” is the result. If untreated, this can spread to the groin/inner thighs by cross contamination of underwear and clothing therby producing what is commonly known as “jock itch”. The fungus can also infect the nails and produce significant nail deformity. If untreated, fungal infections which compromise the integrity of the skin can also lead to serious secondary bacterial infections of the skin. Fortunately, fungal infections limited to the skin are easily treated with topical and sometimes oral antifungal medications. Toenail infections may be more challenging to treat but are often responsive to oral antifungal medications but careful monitoring by a physician is required to watch for possible side effects.
