Fungal nail infection

You may have a fungal nail infection if your nail is brittle, discoloured or thicker than usual. These types of infections are not serious but they can take a long time to treat.

Check if you have a fungal nail infection

Fungal nail infections usually affect your toenails, but you can sometimes get them on your fingernails, too.

Fungal nail infections usually start at the edge of the nail
The infection often spreads to all of the nail, making it thicker and turning it white or yellow
The nail may become brittle and crumbly. The whole nail can sometimes lift off, causing the skin around it to become swollen and painful
