FAQ – Why is my toenail discolored after I run?

Runner’s toe” is a common problem where the small blood vessels under the toenail burst and cause dark, “bruise-like” discoloration to the toenail. It is caused by excessive pressure to the tips of the toes either from long distance running or from the front of the shoe fitting too tight. Sometimes part of the nail or the entire toenail becomes discolored from runners toe.

If increased pressure continues to occur, the nail will become loose and possibly fall off. Changing shoe gear or adding padding to the toes can help resolve runner’s toe.

However, if the nail becomes loose or painful, you should call Advanced Podiatry in Tampa Florida at (813)875-0555 for proper evaluation and care by a foot doctor..
