Black Toenails

A black or darkened toenail usually means that the toenail is bruised. The toenail turns black because there is blood under the nail. Bruising can occur from simply stubbing one’s toe, hitting it on a chair leg, or from running. Runners are prone to black toenails because the toenail rubs against the shoe, especially ill-fitted shoes. Runners should purchase shoes a half size bigger than their normal size to allow from movement of the foot and toes. If a toenail turns black without being injured, get the toenail checked right away. Similar coloring without trauma can indicate melanoma.

The only treatment for a bruised toenail is time. Eventually the nail will grow out. But, a bruised toenail can lead to a fungal nail infection if not properly cared for and cleaned. If the nail is already black, the infection is severe and sometimes the nail will fall off completely. An appointment needs to be made immediately to stop the spreading of the infection by prescription medication. A new toenail will start to grow back in six to nine months.

Fungus can be picked up at any public area, shower, gyms, or saunas. Always wear proper footwear outside to avoid contracting a fungus.
 

Diabetics need to be especially concerned with any changes of the toenails, whether the color turns black or yellow. The pressure causing the bruised nail can lead to a small sore under the toenail which can lead to infection.
