Note: Always check with your physician before attempting to “self-diagnose” your condition. Nail fungus has many different looks, and only your physician is qualified to diagnose it properly. Typical attributes of nail fungus, according to Wikipedia, are as follows:
“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.There is usually no pain or other bodily symptoms, unless the disease is severe. “
Again, always check with your physician for a reliable diagnosis.
