The Sciatic NerveP. Wall

READ 91-B

The sciatic nerve passes from the lower spine to the feet.

It is the longest and widest single nerve in the human body.

Sometimes this nerve is irritated, which produces a feeling of pain, tingling, or numbness. This condition is called sciatica.

Severe sciatica can make walking difficult if not impossible.

Sciatica occurs when a nerve that connects to the sciatic nerve is compressed or irritated.

Sciatica is generally caused by disc disease.

The spine consists of a string of discs.

These discs are filled with fluid which can leak due to age or injury. This is called a “herniated disc.”

Other conditions which can cause sciatica are narrowing of the spinal canal and degenerative disc disease.

These spinal conditions frequently occur with aging.

The good news is that sciatica usually gets better on its own. The healing process usually only takes a few days or weeks.

Pain management techniques and regular exercise will go a long way toward remedying the situation.

If medication and exercise do not resolve the pain, surgery is an option. About 80% of patients find relief through surgery.
