If you think about the mechanics of your neck, you’ll realize it’s not surprising how easily it can be injured. It has amazing flexibility, is constantly on the move, has very little muscular support, but has to support the 14 – 16 pounds of your head. It is like balancing a bowling ball on a stick using only elastic bands.
Consider that your spinal cord runs down a space in the center of the vertebrae, which protects it from harm. Along large bundles of nerves running out from between each pair of vertebrae, nerve impulses are sent to every part of the body. From your cervical vertebrae, impulses are sent to your arms, and some into your upper back. Thus pain in your arm, such as numbness, tingling, cold, aching, or “pins and needles”, may be referred from the neck. People with neck problems may mistake their pain for carpal tunnel syndrome, a condition in the hands that is often caused by repeating the same repetitive motions for long periods.
Neck problems can also lead to headaches, muscle spasms in the shoulders and upper back, ringing in the ears (tinnitus), inflammation in the middle ear (otitis media), temporomandibular joint dysfunction (TMJ), or simply a restricted range of motion and severe tightness in the neck and upper back. Issues from the neck can show up in the upper back because many neck muscles originate there, including the trapezius, the levator scapulae, the cervical paraspinal muscles and the scalenes.
