Low Back Pain and Disc Herniation

The discs located between vertebrae are vulnerable to injury, and can cause debilitating pain when injured.  Disc herniation most commonly affects the lumbar spine, but it can also occur in the cervical spine, and rarely, in the thoracic spine.

What is disc herniation?

Disc herniation is a term that refers to displacement of the nucleus pulposus of the intervertebral disc, due to injury or weakening of the external portion of the disc (annulus fibrosis).  The term “slipped disc” often refers to this type of injury, as does bulging disc.

There are four stages of disc herniation, with various degrees of displacement of the nucleus pulposus. The final stage occurs when the annulus fibrosis is completely ruptured and there is a complete loss of integrity of the external structure.

Pain occurs due to increased pressure on the nerves exiting the spinal cord. Symptoms such as pain, numbness and tingling will occur in the area that is supplied by the affected nerves.

How does disc herniation occur

Disc herniation most often occurs due to injury, sometimes from a seemingly innocent action such as bending over or twisting to pick something up. These actions of sudden flexion or rotation often cause an increase in pressure which forces the nucleus pulposus in a posterior (toward the back) direction.

Signs & Symptoms of Disc Herniation

If you’ve ever had an issue with a disc, it is an unforgettable experience.

1. Sudden, excruciating pain – into the legs and buttocks if the herniation occurs in the lumbar spine; into the arms and hands if the herniation occurs in the cervical spine.
2. Muscle spasm will occur in the injured area – this is the body’s protective mechanism to prevent further injury by immobilizing the area.
3. certain actions will increase pain and symptoms, such as bending forward from the hips, side bending, or twisting. As the action causes the pain, a therapist can tell where the bulge is happening by the pain distribution.

How is disc herniation treated?

Disc herniation is a condition that must be managed in the initial stages, with a focus on removing pressure from the affected nerves and pain control.  As the condition progresses, the focus turns to strengthening the supporting structures – if the herniation has occurred in the lumbar spine, core muscle strengthening will be incorporated into a rehabilitation program.

Massage therapy itself is not a standalone therapy for disc herniation – it can help with pain control and removing some of the excess muscle spasm. It must be noted that removing all of the hypertonicity (excess muscle tone) in the muscles surrounding the injured area is not wise – the excess tone in this case is used to stabilize the area, and if it is completely removed, the area can become very unstable and make the injury worse.

If the injury to the intervertebral disc is severe, the condition can become chronic and progress to degenerative disc disease.
