Ep 6: The Difference Between Pain and Injury (with Dr. Jonathan Fass)

Did you know that your mental and environmental issues can significantly affect your physical pain? We often don’t think of how the fear of moving our backs or knees in a certain way can cause or play into the very thing we’re trying to avoid.

In this episode, I chat with my husband Dr. Jonathan Fass, a doctor of physical therapy, board-certified in orthopedics, and has recently completed his fellowship in orthopedics in manual physical therapy.

He talks about the difference between pain and injury, plus what causes pain. And we discuss what pain means and how to respond to it.


Listen in to learn the importance of moving your body in individualized motions that feel good for you, even if they don’t fulfill everyone’s ideals. You will also learn about pain and why nonspecific pain isn’t always a threat.
