Subacromial bursitis is a common cause of shoulder pain that is usually related to shoulder impingement of your bursa between your rotator cuff tendons and bone (acromion). Your subdeltoid bursa is less commonly inflamed shoulder bursa.
The space where your rotator cuff tendons and shoulder bursa reside (the sub-acromial space) becomes smaller when your arm is raised overhead and pushed to the limit. If pain is felt in your shoulder, the test is considered positive. The pain is likely caused by impingement of the tendons or bursa in that area of your shoulder.
