Shoulder

The shoulder moves more than any other joint in the body, so it relies on the tendons and muscles around it for support. That is why most shoulder problems involve the tendons and the joint lining rather than the bone itself. Pain, difficulty lifting the arm, or pain that stops you sleeping can each have several causes, and each is managed differently.

• 

  Frozen shoulder

  The capsule tightens, so the shoulder moves less. It runs over months.

• 

  Rotator cuff tear

  A torn shoulder tendon: pain outside, pain at night, hard to lift.

• 

  Shoulder pain

  Tendons, capsule or joint. The movements that hurt narrow it down.
