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.
It is formed by the humerus -- upper arm bone -- and the glenoid fossa -- part of the shoulder blade bone. Bursa sacs are small, fluid-filled cushions that provide padding between bones and tendons in a joint to reduce friction and improve movement. Shoulder bursitis develops when the bursa sac becomes inflamed.
