Written by Dr. Jeffrey Peng, MD — Board-Certified Sports Medicine Physician Published: March 1, 2025 | Last Updated: March 1, 2025 Most people who struggle with joint pain are focused on the wrong things. They wait for the pain to go away on its own. They rest for weeks—sometimes months—hoping time will fix the problem. They stretch when they should be strengthening. And they treat the symptoms without ever addressing the underlying system. In my practice, I see these patter

Written by Dr. Jeffrey Peng, MD — Board-Certified Sports Medicine Physician Published: March 1, 2025 | Last Updated: March 1, 2025 Movement is medicine — but most people with arthritis do the exact opposite. When joint pain flares, the instinct is to stop moving: skip the walk, avoid the stairs, rest as much as possible. The problem is that avoidance does not protect your joints. In my practice, I see this pattern regularly — patients who stop moving in an effort to manage t
