Always closely compare right foot vs left foot with a running injury

Just this morning, I was on a second opinion call with a runner who had an issue. He said, “It is only going to take a few minutes. I would not even use the entire time because I have a simple problem.” Every time I do a consultation, I try to see if I can compare the right foot versus the left foot. I wanted to see both of his feet and he just showed me the one that was hurting.  I told him I needed to see the other one and he said it did not hurt and it did not matter, but it does matter. It is super important.  Why should you always compare the right foot to the left foot when you have a running injury?  Well, that is a great question and that is what we're talking about today on the Doc On The Run Podcast.
