Onychomycosis is the medical term for a common fungus that impacts millions of Americans. It can occur with both toe nails and fingernails but is much more common with toes; the estimate is that it affects six to eight percent of the adult population.
A nail fungus infection causes discoloration of the nail and causes it to crumble on the edges as the condition advances. There are both oral medications and topical solutions that are offered as nail fungus treatments. There are also homeopathic options that are designed to combat this particular type of infection.
