Neck problems occur frequently in everyday life. Often by evening, the neck can tire from supporting the skull's weight all day, or from incorrect posture. To compensate, we often rotate, extend and flex the muscles supporting the cervical part of the spinal column without even realizing it.
The cervical portion of the spinal column, or cervical rachis, consists of seven vertebrae, connected and aligned by a system of ligaments and muscles. The spinal cord runs down the inside of the vertebrae and its nerve roots channel into the head, neck and upper arms.

Sensitivity to pain, and impulses controlling muscular movement are carried through the nerve endings. Each change that occurs in the bone, joints, ligaments, muscles or to the nerve endings in the neck can create pain of varying intensity.
Pain can be focused in the neck area (as it does with a stiff neck) or spread along a nerve ending that originates in the spinal column to reach the arms. If the muscular involvement is excessive, pain may extend to the nape of the neck and produce a headache.
