The
amount of neck flexibility, magnified by the fact that it contains
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”.
Most neck and upper back pain is caused by a combination of
factors, including injury, poor posture, chiropractic subluxations,
stress, and in some instances, disc problems.
