My toenail hurts when I run

I just had a consultation with a woman who has been having pain in the toes and the end of the big toenails just after running. The pain in the big toes has been getting worse.  She was also getting some numbness or tingling around the corner of the toenails. She wanted to know…  "Am I doing something wrong with my shoes?” “Am I cutting my toenails wrong?”  “Is there really something wrong on the inside of my toe?"  Today on the Doc on the Run Podcast, we're talking about what you need to think about if your toenail hurts when you run.
