Advice for flat footed runner with plantar plate injury started on a treadmill

I was just on a call with a runner who has a plantar plate sprain. A plantar plate sprain is an injury to a very small ligament right at the base of the toe, usually the second toe, right where it attaches to the metatarsal at what we call the metatarsophalangeal joint. 

That sprain typically causes aching in the ball of the foot.

These are tough injuries to get better.

I have had one myself, and when you get them, they're really annoying.  

It seems like they get better very, very slowly, but you can make them worse very, very quickly. 

It's really important when you get a plantar plate sprain to identify the one thing that caused the injury so you stop doing it.

Today on the Doc On The Run Podcast, we're going to talk about my advice for a flat-footed runner who has a plantar plate injury that started from running on a treadmill.
