Most frozen shoulders get better on their own within 12 to 18 months. For persistent symptoms, your doctor may suggest:
Steroid injections. Injecting corticosteroids into your shoulder joint may help decrease pain and improve shoulder mobility, especially in the early stages of the process.
Joint distension. Injecting sterile water into the joint capsule can help stretch the tissue and make it easier to move the joint.
Shoulder manipulation. In this procedure, you receive a general anesthetic, so you'll be unconscious and feel no pain. Then the doctor moves your shoulder joint in different directions, to help loosen the tightened tissue.
Surgery. Surgery for frozen shoulder is rare, but if nothing else has helped, your doctor may recommend surgery to remove scar tissue and adhesions from inside your shoulder joint. Doctors usually perform this surgery with lighted, tubular instruments inserted through small incisions around your joint (arthroscopically).
