(HealthDay News) — The joints, tendons and muscles that make up the shoulder allow for a lot of flexibility. But an injury or a number of medical conditions can cause pain and limit the shoulder’s movement.
The American Academy of Orthopaedic Surgeons says common reasons for shoulder pain include:
- Tendinitis, the inflammation of a tendon in the shoulder.
- Bursitis, the inflammation of a sac of fluid in the shoulder that’s designed to limit friction during shoulder movement.
- An injury that leaves the shoulder joint out of position or unstable.
- Arthritis in the shoulder.
