Fungal Nail: Fungal nail, Onychomycosis, is a common disease of the toenail, cause by skin fungus which has moved underneath the nail. Normally, the nail adheres to the nail bed and provides a natural barrier to fungal infection. However, even a minor trauma (repeated bumping of the nail on the inside of shoes) can gently lift the nail and make it vulnerable to fungal infection.Fungal nails may appear thick & bumpy, and the discoloration can be yellow, brown or black in color depending on the type of fungus involved. Infection usually starts at the tip of the nail and progresses towards the nail root, causing destruction as it travels. Occasionally, there may be an unpleasant odor. The nail may separate and even fall off completely.The condition is generally painless and often ignored. A fungal nail however, shares the same sock and shoe as the rest of the foot, thus infection of other nails can occur.
Treatment for fungal nail includes filing down & debriding the nail, and controlling surface fungus.
