Subacromial space injection: pain reliever, diagnostic tool.
Some of the most common presentations in a primary care office relate to shoulder pain; disorders of the rotator cuff and potential look-alikes such as referred neck pain or acromioclavicular (AC) joint arthritis are chief among the causes. The differential diagnosis can be difficult, particularly among older patients. And, of course, patients want relief of pain. Subacromial space injection using anesthetic with or without corticosteroid can assist in both phases of management.
