There are some nonoperative, conservative options to consider for the treatment of a rotator cuff tear or shoulder instability:
Ice packs. Reduce swelling while resting the arm.
Anti-inflammatory medications. Decrease swelling in the joint and provide temporary pain relief. Please note, however, that all medications have risks and should be taken only in consultation with your pharmacist and physician.
Physical therapy. Helps shoulder to regain normal motion and strengthens muscles.
