Shoulder pain is a common complaint among adults. People who play sports or do a lot of heavy lifting at their job may be more susceptible to pain in the shoulder than others. However, nearly everyone will encounter shoulder pain at least once in their lifetime. Shoulder pain causes can vary from chronic overuse to bone fractures, soft tissue injuries, and disease. Your shoulder is made up of bones, muscles, tendons, and ligaments that work together to allow joint mobility.
Your shoulder is one of the body’s most mobile joints, allowing arm movement and flexibility. Shoulder pain can occur suddenly with an injury or progress over time with repetitive use. Muscles can be strained, small tissue tears can become inflamed, and your shoulder bones (the humerus, scapula, and clavicle) can become dislocated. Other common conditions that often cause shoulder pain include:
- Bursitis (joint inflammation)
- Tendinitis
- Rotator cuff injuries
- Pinched nerves
- Bone spurs
- Fractures
- Shoulder dislocation or separation
- Cartilage and muscle tears
- Impingement
- Osteoarthritis
- Rheumatoid arthritis
- Spine or disc issues
- Frozen shoulder (severe stiffness and pain in the shoulder joint)
