What are the causes of shoulder bursitis?
You may have tendinitis (inflamed tendons) and bursitis in your shoulder at the same time. Your bursitis may be part of a problem called shoulder impingement (im-PINJ-ment). This occurs when the rotator cuff (shoulder muscles and tendons) is inflamed and squeezed between the shoulder bones. This can lead to irritation of the bursa. Following are some common causes of shoulder bursitis: • An injury of the shoulder or falling on your outstretched arm. • Age. Shoulder bursitis is more common in people as they become older. • Infection (in-FEK-shun). • Overuse of the shoulder in sports such as tennis, swimming and baseball, especially from pitching and throwing. Overuse can happen by doing activities that cause you to raise your arms over your head a lot. These activities include hanging wallpaper and painting. • Rheumatoid arthritis (ahr-THREYE-tis). Bony growths on your shoulder bones may rub against and irritate the bursa and tendons. What are the signs and symptoms of shoulder bursitis
