Signs and symptoms of a fungal nail infection

A fungal nail infection may not cause any obvious symptoms at first.

As it progresses, the infection can cause:

·discolouration of the nail – it may turn white, black, yellow or green

·thickening and distortion of the nail – it may become an unusual shape or texture and be difficult to trim

·pain or discomfort – particularly when using or placing pressure on the affected toe or finger

·brittle or crumbly nails – pieces may break off and come away completely

Sometimes the skin nearby may also become infected and be itchy and cracked or red and swollen.
