Abnormal Nails - Toenail Conditions

How is the condition diagnosed?

Most nail conditions are easily diagnosed by looking at the nail. A diagnosis of thickened and discolored nails may be more difficult. Most of the time, nail conditions are the result of a fungal nail infection. Sometimes, nail conditions indicate an underlying disease. A healthcare provider such as a podiatrist, or foot specialist, can usually best diagnose nail conditions. A history and physical exam, and sometimes a biopsy, are done.
