Why Rest Won't Fix Your Knee or Back Pain with Dr. Tom Walters

Summary Dr. Tom Walters, a board-certified orthopedic physical therapist and the founder of Rehab Science, returns to talk through two of the most common complaints after 40: knee pain and back pain.

We get into why rest alone rarely fixes either one, how cartilage actually gets its nutrients through movement, and how to tell a tendon problem from something deeper in the joint.

Tom explains load management, the real reason most aches show up without a specific injury, walks through the red flags that mean you should see someone for back pain, and covers how stress and sleep feed into chronic pain.

He also shares his three tactics for staying well: social support, exercise, and sleep.
