Warning Signs Of Athlete's Foot

Discolored And Thick Toenails

A final warning sign of athlete's foot can be noticed in your toenails. Because the fungus eats keratin, your nails are in just as much trouble as your skin. When the nails are subjected to trauma or infection, they start to die. This dying process is usually noticeable by the hardening it goes through. You may notice the nail even begins to become thick. Discolored and thick toenails are a sign the fungus has migrated to the nails. It's also possible you became infected underneath the nail. This is especially true if you shared a sock or shoe with someone who is infected with athlete's foot.
