It's an infection

Onychomycosis is a fungal infection, usually of the toenails, that is progressive. Fungal nail infections are estimated to account for up to 50% of all nail problems.

It must be treated

A fungal infection is progressive and generally does not go away on its own. If left untreated, it can cause pain and mobility problems, like difficulty walking. Show your symptoms to a doctor as soon as possible.

It's contagious

The fungi that cause nail infections can be transmitted from nail to nail and to the surrounding skin. The risk of exposure to the type of fungi that cause infection is high in areas like locker room floors and public pools.

Next step

If you suspect you have a toenail fungus infection, you should see a doctor at the first signs.
