In most cases, initial treatment is nonsurgical. Although nonsurgical treatment may take several weeks to months, many patients experience a gradual improvement and return to function.
Rest. Your doctor may suggest rest and activity modification, such as avoiding overhead activities.
Non-steroidal Anti-Inflammatory Medicines. Drugs like ibuprofen and naproxen reduce pain and swelling.
Physical Therapy. A physical therapist will initially focus on restoring normal motion to your shoulder. Stretching exercises to improve range of motion are very helpful. If you have difficulty reaching behind your back, you may have developed tightness of the posterior capsule of the shoulder (capsule refers to the inner lining of the shoulder and posterior refers to the back of the shoulder). Specific stretching of the posterior capsule can be very effective in relieving pain in the shoulder. Once your pain is improving, your therapist can start you on a strengthening program for the rotator cuff muscles.
Steroid Injection. If rest, medications, and physical therapy do not relieve your pain, an injection of a local anesthetic and a cortisone preparation may be helpful. Cortisone is a very effective anti-inflammatory medicine. Injecting it into the bursa beneath the acromion can relieve pain.
