That tip is: Exercise...
Yup! Stay active!
If you have had a knee injury, back, neck or shoulder strain, I know that you may feel just a bit reluctant to exercise; thinking that it could cause you more harm than good. But the opposite is true!
Strengthening the muscles that support these structures, and keeping them flexible, is the best way to prevent further injuries. Plus - exercise releases Endorphins that will help modify and reduce your pain.
Just don't be a hero, and don't overdo it when it comes to exercise. Start slowly. Do normal functional movements like walking, mild yoga, or exercise moderately with weights, and build your strength over time.
Remember: Muscle soreness after a workout is normal, but any kind of sharp, shooting, or sudden pain in the muscles or joints (especially during the act of exercise) may be a sign that something is wrong. If you experience this type of pain while exercising, I want you to stop right away and check with your doctor before resuming activity again.
