How to recover from a rotator cuff injury?

Rest and exercise: As long as it is not torn, a cuff sprain/strain resolves with rest for a couple of days with the use of anti inflammatory meds, followed by gradual exercises involving rotation of the shoulder (look up codmans exercises, which are pendulum exercises for the shoulder). Perform slowly, as pain resolves, can add light weights while performing them to strengthen rtc muscles.

Physical Therapy: Physical therapy is the mainstay of treatment for rotator cuff strains. I personally have not found injections of cortisone very effective.. These can sometimes take 3-6 months to improve.
