What Causes Them?
Several different fungi can lead to a nail disorder, as the pathogens enter the skin through very tiny openings between the nail and nail bed. If the surrounding area is warm, moist, and unventilated, the fungi propagate quickly. Other contributing factors for nail disorders include family history, walking barefoot in public areas, or profuse sweating. Even poor health can contribute to the development of these conditions, as diabetes and poor circulation are known triggers.
