If the pain doesn't go away, an injection of cortisone into the joint may help. Cortisone is a strong medication that decreases inflammation and reduces pain. Cortisone's effects are temporary, but it can give very effective relief in the short term. Your doctor may also prescribe sessions with a physical or occupational therapist. Your therapist will use various treatments to calm inflammation, and including heat and ice.
Therapists use hands-on treatment and stretching to help restore full shoulder range of motion.
Improving strength and coordination in the rotator cuff and shoulder blade muscles lets the humerus move in the socket without pinching the tendons or bursa under the acromion. You may need therapy treatments for four to six weeks before you get full shoulder motion and function back. If you are still having problems after trying conservative treatments, your doctor may recommend surgery. The goal of surgery is to increase the space between the acromion and the rotator cuff tendons. The surgeon must first remove any bone spurs under the acromion that are rubbing on the rotator cuff tendons and the bursa.
