What is Sciatica?

The sciatic nerve is the longest and largest in the human body, roughly the width of a thumb. It runs from the low back, out through the pelvis and down the leg into the foot. It is made up from nerve roots from five separate spinal levels at the bottom of the spine (L4 to S3). These joint together to form the sciatic nerve. The nerve has both a sensory and a motor component, providing sensation and movement to the legs.

Sciatica is usually pain, numbness or tingling in the low back, legs or feet. These symptoms are caused an inflammation of the sciatic nerve. This can happen by compression, damage or irritation of the nerve anywhere along its path.

What Causes Sciatica?

Spinal Stenosis: Narrowing of the spinal canal causing compression.

Spinal degeneration of the joints: Causing a narrowing where the nerves exit the spinal canal.

Disc prolapse or herniation: these bulges can press on the nerves as they exit the spinal canal.

Spondylolistheses: Where one vertebrae slips forward over another one.

Degenerative disc disease: reducing the cushioning effect of the discs so that the nerves have less space.

Piriformis syndrome: The piriformis is a muscle which passes over the sciatic nerve in most people. If it becomes too tight it can compress the nerve.

There are many more causes of sciatica, including some which are serious, and conversely not all leg pain is caused by sciatica, so it is essential that you consult a Chiropractor, GP or other qualified professional to examine you thoroughly and establish the cause before beginning any treatment.
