Worst advice ever from a doctor

I talk to lots of runners who have been given very bad advice. 

If you are reading this, you are probably a runner, and you have probably had to deal with some kind of injury that interfered with your running.

If you have seen a doctor, I am very curious to know what advice you got.

Sometimes I am curious if the "bad advice" is what the doctor said, or if it is just a misinterpretation of what the doctor said to the runner. 

Today on the Doc On The Run Podcast, we're talking about the worst advice ever from a doctor.
