The disc (or intervetebral disc) is a structure that is found in between the spinal vertebral bodies from the
neck to the sacrum (tailbone). The disc serves as a cushion and helps the spine to move. A single disc and its
two vertebral bodies does not have much ability to move, however, when put together along the length of the
spine, the amount of movement provided is considerable. Disc herniations are abnormal protrusions of a portion
of the disc material and can cause pain and additional symptoms,
The most common symptom of a cervical(neck) disc herniation is neck pain that radiates (spreads) down to the
arm in various locations. The specific location of the arm pain depends on which disc is involved. Aternately,
the most common symptom of lumbar (low back) disc herniation is low back pain that radiates down the leg. There
can also be associated paresthesias (pins and needles) and in some cases weakness of some of the arm muscles.
In most cases, conservative treatment including physical therapy can resolve the problem. Physical therapy can
consist of traction, mild _stretching, stabilization exercises, manual therapy, and modalities. These
can be using in various combinations depending on the patient.
