The most common infection of the nails is caused by a one-cell plant called fungus. Fungal nail infections or onychomycosis, are more common on the toenails than the fingernails and affects about 12% of all Americans. It occurs in approximately 25% of people at age 40 and 40% of older people. Onychomycosis tends to run in families because of an inherited tendency but not everyone is susceptible. The first symptom of fungal infection in the nails is the appearance of yellow or white spot commonly seen under the tip of the affected toenail or fingernail. Eventually, if left untreated the fungus will go deeper into the nail. As a result, the whole nail will have discoloration, will thicken and will build crumbling edges which can be a start of a very painful nail dilemma.
