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.
This will cause pain in the collarbone but also in the shoulder and sometimes in the upper chest. Bursitis: A bursa is a sac that provides a cushion to joints and muscles. Bursae can become swollen and painful after injuries. Bursitis of the shoulder may cause pain to radiate to the chest. Sometimes the smaller bursae in the chest wall can become inflamed and cause pain. Heart attacks: Although the problem is the heart, heart attacks can cause referred pain to the shoulder or neck.
