Neck pain is pain that starts in the neck and can be associated with radiating pain down one or both of the arms. Neck pain can come from a number of disorders or diseases that involve any of the tissues in the neck, nerves, bones, joints, ligaments or muscles. The neck region of the spinal column, the cervical spine, consists of seven bones (C1-C7 vertebrae), which are separated from one another by intervertebral discs. These discs allow the spine to move freely and act as shock absorbers during activity.
Each vertebral bone has an opening forming a continuous hollow longitudinal space, which runs the whole length of the back. This space, called the spinal canal, is the area through which the spinal cord and nerve bundles pass. The spinal cord is bathed in cerebrospinal fluid (CSF) and surrounded by a protective layer called the dura, a leathery sac.
Neck pain may be caused by arthritis, disc degeneration, narrowing of the spinal canal, muscle inflammation, strain or trauma. In rare cases, it may be a sign of cancer or meningitis. For serious neck problems, a primary care physician and often a specialist, such as a Physiotherapy Specialist, should be consulted to make an accurate diagnosis and prescribe treatment.
