fungal nail infections

a fungal nail infection is a fungus that gets into your fingernail, toenail, or the skin under your nail, usually through a small cut.

the infected toenail usually turns white or yellow. sometimes it's painful.

toenails that are exposed to moisture and warmth a lot may be more likely to get infected by a fungus. this can happen from wearing sweaty shoes often.

toenail fungus usually doesn't need treatment unless it's causing pain. it often comes back after it has cleared up.
