A fungal nail infection occurs when a fungus invades a fingernail or
toenail. Causes include:
Walking barefoot in public places.
Athlete's foot infection spreading to the nails.
Moisture can collect under artificial nails, especially if they are left on for
3 months or longer. Trapped moisture will encourage the development of a fungal
nail infection. The natural nail may separate from the artificial nail.
Symptoms of a fungal nail infection include cracked, yellow,
discolored, streaked, thickened, or spotted nails.
Fungal nail infections do not usually get better without treatment.
The infection may spread to other parts of the nail and nail bed. Early
treatment may lead to a faster cure with less permanent nail damage.
Home treatment may help.
treatment for fungal nail infections include:
Oral antifungal medicine, such as
itraconazole, griseofulvin, or ketoconazole.
Topical application of
an antifungal cream or ointment.
Surgical removal of the infected
