Most people assume shoulder pain means there is something wrong with the shoulder joint.
Sometimes that is true. But in many cases, pain felt in the shoulder can start in the neck.
The neck and shoulder share muscles, nerves, and movement patterns. When one area becomes irritated, the other area may feel the pain. This is called referred pain.
A person may feel pain in the shoulder even when the main problem is coming from the neck.
Several nerves leave the cervical spine and travel through the shoulder before continuing into the arm and hand.
When one of these nerves becomes irritated, symptoms may show up far away from the source of the problem.

Treatment depends on what is causing the symptoms.
Some patients need care focused on the neck. Others need treatment directed toward the shoulder, posture, or soft tissue tension.

The goal is to improve movement, reduce irritation, and find where the symptoms are coming from.
