What is Nail Fungus?

Nail fungus, or onychomycosis, can occur on both the toenails and fingernails with the majority of cases typically affecting the toenails.

A fungal nail infection is characterized by the nail becoming thickened and appearing discolored with the nail, then becoming brittle and coming away from the toe or finger as the condition progresses. The skin may become inflamed andpainful if left untreated. The condition can impair walking and wearing shoes.

Spa showers, swimming pools and locker rooms where people walk barefoot are some of the places a person can get a nail fungal infection. It is important to always use protective foot covering when in these types of areas.


For a mild fungal infection, daily cleaning and over-the-counter products may be helpful. In more severe cases oral antifungal medications may need to be prescribed. Removal of the infected nail may be necessary in severe cases.
