#1 most worrisome problem with toenail lost to running

Have you ever had a toenail turn black and blue, and maybe even got so much of a bruise that the toenail fell off? A lot of runners think of bruised toenails as a badge of honor for doing super long runs and completing marathons. But you do not want toenails to fall off! Believe it or not, I have had runners ask me  if I would permanently remove their toenails so that they would no longer get black toenails. But I do not recommend it. What is the number one most worrisome problem when you lose a toenail from running?  Well, that is what we're talking about today on the Doc On The Run Podcast.
