What is Onychomycosis / Nail Fungus?
The most common symptom of a fungal nail infection is the nail becoming thickened and discoloured: white, black, yellow or green.
As the infection progresses the nail can become brittle, with pieces breaking off or coming away from the toe or finger completely.
If left untreated, the skin can become inflamed and painful underneath and around the nail.
There may also be white or yellow patches on the nail-bed or scaly skin next to the nail and a foul smell. There is usually no pain or other bodily symptoms, unless the disease is severe.
People with onychomycosis may experience significant psychosocial problems due to the appearance of the nail, particularly when fingers which are always visible rather than toenails are affected.
