Germs and Infections You Could Catch at the Gym
What It Is: The most common cause of toenail fungus is distal subungual onychomycosis, the same fungus that causes athlete’s foot. And like athlete’s foot, it is commonly contracted from locker room floors and wet surfaces near pools. Symptoms: You’ll notice a change in the texture of your toenails. Your toenails may become thickened and yellow, and may also have a crumbly texture.
