If a fungus invades the toenail and/or the nail bed, the toenail becomes yellow, thickened, and eventually deformed if not treated. Commonly, the fungus is the same fungus responsible for athlete's foot. The infection starts at the top of the nail and works its way back, generally invading the matrix (nail bed), distorting the growth of the nail. There is relatively no pain associated with fungal nails and often they go unnoticed. Sweaty feet are the main culprit. Treatment generally involves clipping away the diseased portion of the nail and applying an antifungal medication. Over-the-counter and prescription oral and topical medications can also provide some relief but may not clear up the infection.

Foot Tip: Keep feet clean and dry. Change socks daily. Keep common shower areas clean and do not share shoes and socks

Treatment includes painless debridement, topical and/or oral medication or fungal nail laser therapy. Ask your podiatrist for available treatments appropriate to your problem.
