When Shoulder Pain May Actually Be Coming From the Neck

Overlapping Referral Territory

The cervical spine and the shoulder share closely overlapping segmental innervation, meaning irritation of cervical structures — facet joints, nerve roots, or the discs between vertebrae — can refer pain into the shoulder region in a pattern that can be difficult to distinguish from a genuine shoulder joint problem on symptom location alone.

Clues That Point Toward the Neck

Cervically referred shoulder pain is more likely when symptoms are reproduced or aggravated by neck movement rather than shoulder movement, when there is associated neck stiffness or headache, and when shoulder special tests are inconsistent or fail to reproduce the familiar pain despite a seemingly clear shoulder-related history — findings consistent with the broader concept of regional interdependence between the cervical spine and shoulder girdle (Sueki et al., 2013).

Why Missing This Stalls Recovery

Treating the shoulder in isolation when the cervical spine is a significant contributor is a common and entirely avoidable reason that shoulder rehabilitation can plateau — reinforcing why a competent shoulder assessment always includes active screening of the neck.
