Toenail fungus can be a miserable problem to live with. It can mangle your toenails for years, or even decades. It looks awful, it feels awful, it can even smell awful.
Nail fungus is a common condition that begins as a white or yellow spot under the tip of your fingernail or toenail. As the fungal infection goes deeper, nail fungus may cause your nail to discolor, thicken, and crumble at the edge. It can affect several nails. If your condition is mild and not bothering you, you may not need treatment. If your nail fungus is painful and has caused thickened nails, self-care steps and medications may help. But even if treatment is successful, nail fungus often comes back.
