Black Toe

Symptoms of Black Toe

The most obvious symptom of black toe is a black or dark blue color on part or all of the toenail caused by bruising or pooling of blood under the nail. Since black toe most frequently is a result of trauma to the toe or the nail, it may be accompanied by pain or discomfort that usually diminishes within a few days. Black toe may also occur after prolonged periods of vigorous activity even without noticeable trauma or pain.

In some cases, discoloration of the toenail can result from causes other than black toe, some of which are benign. Others, such as the rare disorder, subungual melanoma, are cause for concern. See Medical Considerations for Black Toe for more information.
