Nail coloration: Common causes of nail discoloration include bleeding under the nail (from bumping the toe) or chronic fungal infection, which both thickens and discolors the nail. With fungus infection it usually darkens by becoming opaque and whitish first; it bruises more easily and become dark from blood beneath the nail, and over time may develop yellowish or greenish discoloration from the fungus.

It depends: Why they are dark? It can be fungus? It can be dried blood, it can be bacterial colononization. Usually, a podiatrist or dermatologist may sample the nail and material under the nail to arrive at a diagnosis and then base therapy on that pathology report.

Think fungus: Fungal infections of the nail(s), or onychomycosis. A podiatrist can make the diagnosis, and offer treatment options.

Sounds like fungis: Keep in mind... The fda has recently come out with a blanket statement that toenail fungus can not be cured. It is "managed" by a number of modalities, but it can always come back in the future.

Dr. Bradly Shollenberger

Fungus: Trauma and various dermatologic problems can cause thickening and darkening of nails, but the most common cause is toenail fungus. Dermatophyte fungi infect the nail, essentially eating it and discarding the debris underneath. This causes the nail to thicken and discolor. The most effective treatment is oral antifungal medication. Lasers have become popular, but are expensive and not permanent.
