Your neck hurts and yet it’s not the problem. If anything, your neck has been doing a great job of picking up more than its fair share of load and range of motion. Neck pain results from the neck compensating for other structures in the body. The structures are not doing their job. Restrictions and decreased mobility of the tissues of the chest and sternum, ribcage, shoulders and thoracic spine (upper and mid back) force the neck (cervical spine) to over-exert. Moreover, this increased compensation and exertion is further exacerbated as it works over-time over the course of a long day. It is important to identify and treat all the associated structures responsible.
A proper examination will identify associated structures that are not performing as intended. Once these structures "free up," the neck may also need some hands-on work and exercise to restore full and efficient movement.
