- They may send you to an orthopedist (bone and joint doctor).
- A physical therapist can help with exercises to rebuild strength and motion.
Back to school, work, or sports
- School or desk work is often OK within days. Jobs with lifting may need light duty for a while.
- Go back to sports only when your doctor says it's OK and you have full motion and strength without pain.
