Most people do not realize how much they move their neck during the day until they are unable to do so. The degree of flexibility of the neck, coupled with the fact that it has the least amount of muscular stabilization and it has to support and move your 14 – 16 pound head, means that the neck is very susceptible to injury. You can picture your neck and head much like a bowling ball being held on top of a stick by small, thin, elastic bands. It doesn’t take much force to disrupt that delicate balance.
The spinal cord runs through a space in the vertebrae to send nerve impulses to every part of the body. Between each pair of cervical vertebrae, the spinal cord sends off large bundles of nerves that run down the arms and to some degree, the upper back. This means that if your arm is hurting, it may actually be a problem in the neck! Symptoms in the arms can include numbness, tingling, cold, aching, and “pins and needles”.
These symptoms can be confused with carpal tunnel syndrome, a painful condition in the hands that is often found in people who work at computer keyboards or perform other repetitive motion tasks for extended periods. Problems in the neck can also contribute to headaches, muscle spasms in the shoulders and upper back, ringing in the ears, otitis media (inflammation in the middle ear, often mistaken for an ear infection in children), temporomandibular joint dysfunction (TMJ), restricted range of motion and chronic tightness in the neck and upper back.
We associate the neck and upper back together, because most of the muscles that are associated with the neck either attach to, or are located in, the upper back. These muscles include the trapezius, the levator scapulae, the cervical paraspinal muscles and the scalenes, as well as others.
