Where Does Neck Pain Come From?
Let’s first look at the anatomy of the neck in order to better understand the structures of the cervical spine that can generate pain. Starting at the back of the spine, the facet joints allow us to move our neck and head in all directions, and each facet joint is surrounded by a joint capsule that is rich with nerve endings and when swollen, can generate pain both locally and radiating. One study of volunteers with existing neck pain looked at the various pathways that pain travels when investigators injected each individual facet joint capsule with normal saline solution. Interestingly, the subjects felt pain in parts of the body other than just the neck. For example, injecting the C6 facet joint capsule consistently reproduced radiating pain down the arm into the thumb side of the forearm and hand, similar to when a disk herniates and a nerve root is pinched. The primary difference was that a deep aching pain occurred in this area, as opposed to a more ...
