Why is my toenail turning black?

Some of the more common causes of a toenail turning black are centered on physical trauma. When a toe experiences trauma, either through repetitive motion or a single event, the nailbed can become bruised or blood can begin to pool between the nail and its bed (which is known as a subungual hematoma). Black toenails are frequently experienced by runners who train long distances.

Darkened nails could also be an indication of a fungal infection. In rare cases, the dark coloration is the indication of malignant melanoma. Although this is not common, it can be quite serious, and is a good reason to always have discolored nails evaluated.

Most subungual hematomas do not require much with regard to treatment. However, the condition can cause discomfort, so you may want to have the pool of blood safely drained. We can perform any care you need here at our Richardson, TX foot doctor office. Call Richardson Podiatry Associates at (972) 690-5374 for more information or to schedule an appointment.
