What causes shoulder pain?
The shoulder is the most mobile joint in the body, which also makes it easy to overload. Pain at the side of the upper arm usually points to the rotator cuff or bursa, pain at the top of the shoulder to the AC joint, and deep, stiff pain in every direction to frozen shoulder or arthritis.
Because several problems can overlap in one shoulder, an accurate diagnosis matters. Ultrasound at the exam table lets us watch the tendons move and pinpoint which structure is causing your pain.
When to see an orthopedic doctor for shoulder pain
- Pain that lasts more than two weeks or keeps coming back
- Night pain, especially lying on the sore side
- Trouble reaching overhead, behind your back, or out to the side
- Weakness lifting the arm or a painful catch as it moves
- Stiffness that keeps getting worse
Get urgent care instead if you have
- A visibly deformed shoulder after a fall or dislocation
- Sudden inability to lift the arm after an injury
- Shoulder or arm pain with chest pressure, shortness of breath, or sweating (call 911)
