Sciatica is defined as the sensation of pain, tingling, or numbness in the back and/or buttocks that radiates down the legs which is produced by an irritation of the sciatic nerve. The sciatic nerve is made up of the nerve roots that extend out of the spinal cord and into the lower portion of the back. The sciatic nerve also branches through the buttocks and down the back of each leg to the ankle and feet. Other causes of sciatica may include herniated, bulging, or degenerated discs, which induce pressure on the sciatic nerve, small, bony growths on the spine (bone spurs) and the compression or pinching of the nerve through injury. In some cases, sciatica may be caused by tumors, pregnancy, or the narrowing of the spinal canal known as spinal stenosis.

 Spinal Injury Susceptibility

Age:

As we grow older, the discs may dehydrate, losing flexibility and the ability to act as cushioning between the vertebrae. Adequate water and nutrient intake, avoiding smoking, and maintaining good posture are things we can do to prevent disc degeneration.

Activities:

Work or recreational activities can put us at further risk of injury. An increase of physical stress or recreational risk increase the chances of damage to the soft tissue of the spine.

Exercise:

Lack of exercise can cause the muscles supporting the spine to weaken, making your back vulnerable to injury and degeneration. Maintaining muscle tone with regular exercise can decrease the chances of an injury.

Diet:

A healthy balanced diet, with appropriate supplementation, will help ensure that your bones and tissue are receiving proper nutrients, thus reducing the chance of injury and degeneration.
