If you are running with foot or ankle pain, and you're trying to figure out what's wrong, the first step is deciding if it is a bone injury or  soft tissue injury. 

Well, that's what we're talking about today on the Doc On The Run Podcast. 

I recently did an episode where I was talking about Lister’s corns.

If you missed it, a "Lister's corn" is really just a callus or thick skin that looks like the pinky toenail or the little toenail has a split in it. 

That edge of the nail that looks like a completely separate piece of nail.

But it's not a nail at all, it's callus.

Why does a lister’s corn hurt when I run? 

All overtraining injuries are difficult. 

The problem is that you're trying to not lose your running fitness while giving the injured part enough of a rest so it can actually heal.

I was recently doing a second opinion consultation with a runner over a webcam to review the MRI of his foot. 

He asked me was really good question:

Every runner who gets injured is in a race against time.  

It is a race to not lose your running fitness. 

Anytime doctors see persistent swelling and pain after an ankle injury, they become concerned there might be a fracture. 

When should a runner who rolled an ankle be concerned that there might be a fracture like a lateral process fracture? 

Well, that's what we're talking about today on the Doc On The Run Podcast.

If you are a runner with pain in the ball of the foot at the base of the second toe and start researching online, you may become concerned you have a thing called a plantar plate injury. 

If so, you may be wondering whether X-rays or MRI imaging may be needed to tell what is wrong. Before seeing a doctor, it may be helpful to understand which are helpful, and which imaging studies are a waste of time. 

What is the worst possible medical imaging study you could get if you're a runner with a suspected plantar plate injury? 

Well, that's what we're talking about today on the Doc On The Run Podcast. 

Just this week, I got a call from an injured runner about a new problem. I've seen him before for some other issues, but in this case.

He said that he thought maybe he actually had an ingrown toenail on his pinky or that the toenail itself had split in half and it was bugging him a little bit.

I said “Well, send me a picture. I'll take a look and see.”

My pinky toenail split in half. Is that a problem?

Well, that's what we're going to talk about today on the Doc On The Run Podcast. 

Today's episode comes from a YouTube viewer who posted a question, 

Today's episode comes from a YouTube viewer named John, who wrote in with a question about nerve pain vs. peroneal tendon pain. 

Well, that's what we're talking about today on the Doc On The Run Podcast.
