When Toes Turn Dark. Nails change colors for multiple reasons. The most common culprit for a black toenail is blood under the hard tissue. Damage to the end of the toe causes blood to leak through the nail bed and stain the keratin a dark color. This is also known as a subungual hematoma, or a bruise under the nail.
When to See Your Doctor. Often a black toenail will eventually fall off and regenerate on its own. If pain or signs of infection (e.g., pus, discharge, foul odor, fevers, chills) are not present, you may not need to seek medical treatment right away. Even so, keep in mind that when the nail returns it may be abnormal as a result of the trauma.
