SN instructed patient you can do many things to help knee pain, whether it's due to a recent injury or arthritis you've had for years. Too much rest can weaken your muscles, which can worsen joint pain. Find an exercise program that is safe for your knee. Do exercise, don’t risk a fall. A painful or unstable knee can make a fall more likely, which can cause more knee damage. Curb your risk of falling by making sure your home is well lit, using handrails on staircases, and using a sturdy ladder or foot stool if you need to reach something from a high shelf.
