Shoulder Impingement Syndrome
To diagnose SIS, a doctor will review your symptoms and perform a physical exam. An impingement test, which involves injecting a local anesthetic into the bursa, can help to confirm the diagnosis.
X-rays or an MRI of the shoulder may also be used to confirm a diagnosis. The MRI may show fluid or inflammation in the bursa and rotator cuff. In some cases, partial tearing of the rotator cuff will be visible.
