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 toenails than the fingernails. Symptoms of onychomycosis can be lifting of the nail, nail discoloration or thickening and deformed nails.
Treatment: Topical antifungal creams, lotions, gels and lacquers may be used, however, it is difficult for them to penetrate the nail. Oral medications can be prescribed and may require monitoring with blood tests. Debridement or removing the infected part of the nail may enhance the effectiveness of the treatments and is used only if the infection is very severe. Making an appointment with your dermatology provider is recommended for treatment of nail fungus.
