Short Answer
It can be related when shoulder stiffness repeats with neck pain, jaw pain, or headache.
How to think about it
Jaw-area muscle tension often appears within the same pattern as neck and shoulder muscle tension. Posture, clenching, and stress can make the jaw, neck, and shoulders tighten together.
