Understanding the 16 Common Causes of Shoulder Pain

The shoulder is incredibly mobile: several joints connect to many muscles and tendons for a large range of motion. This doesn't mean, however, that excessive or unusual activity won't cause shoulder pain and other issues.

Some people with shoulder pain feel it constantly, while others only experience it when they move their arm. A doctor might prescribe temporary inflammation that needs rest or discover that a more serious problem is at play. Each of the conditions that cause pain in the shoulder presents unique symptoms.

1. Bursitis

Bursae are tiny, fluid-filled sacs that line joints and cushion the bones. Excessive movement can cause swelling, and inflammation of the bursa in a part of the shoulder called the rotator cuff. The pain usually goes away after a few weeks with rest, though it may flare on occasion.
