What Causes Black Toenails?
Toenails turn black when a pool of blood collects
underneath the nail. Black toenail problems
are fairly common for runners, hikers, and skaters.
The problem typically occurs when a toe is hitting
or rubbing against the tip of a shoe, boot or skate
for an extended period of time.
