Why do my toenails bruise after a run?

Most runners have to deal with a fair share of problems. A black and blue toenail is a very common problem and while it may be unsightly or alarming, there is usually a reason why it is happening.

This toe problem often occurs with runners who consistently run longer distances. The bruised toenail is due to blood pooling under the nail and is caused by the constant pressure and rubbing of your toe on the end of your shoe. A hot spot on the back of your heel can turn into a blister but with a toe, the blood blister has nowhere to go so the blood remains under the nail. If you run in hot weather where your feet would swell or do a lot of downhill running, there is a higher risk of this problem.

To treat a bruised toenail, the best thing to do is to leave it alone. Keeping it clean and away from further pressure will most likely allow it to heal properly. The nail may fall off and a new one would then grow in place. If the pressure or pain becomes severe, you will need to call Dr. Danciger for further treatment.
