Fungal infections can affect one or several nails and are often painless to begin with. As it grows, the fungus spreads up the finger or toe towards the knuckle or toe joint.

Sometimes fungal infections are mild, causing thickening and slight discolouration of the nail, but nothing more.

Other changes to the nail may include:

Change in colour, becoming yellow, green or black (especially if dirt gets underneath it);
Patches of white may appear where the nail has come apart from the skin underneath;
Bits of the nail or the whole nail may crumble and fall off;
Thickening or formation of ridges on the nail.

Nearby skin may become infected, swelling up and becoming scaly. It may also be painful to walk.
