Understanding Sciatica

Sciatica in Chiropractor: Sciatica is nerve pain that starts in the lower back and travels—visual guide

Sciatica is nerve pain. It starts in your lower back. It shoots down your leg.

Related glossary terms: Herniated Disc, Spinal Stenosis, Nerve Compression.

The sciatic nerve is the longest nerve. It runs from your lower back. It goes through your buttocks and down each leg.

This nerve can get squeezed or hurt. That causes pain, tingling. Or numbness. You may feel weak too.

Sciatica is not a disease. It's a sign of another problem. That problem could be a herniated disc (a bulging cushion in your spine).

It could also be spinal stenosis (a narrow spine). Or piriformis syndrome (a tight butt muscle).

How Sciatica Works?

Most people feel sciatica on one side. The pain can be mild or very bad.

Bad pain makes it hard to walk. It can hurt to stand or sit. Some feel burning or sharp shocks.

Others feel a dull ache. Or their leg goes numb. The nerve also controls muscles.

So sciatica can make your leg weak. That makes it hard to move your foot.

The sciatic nerve starts in your lower back. Nerve roots join to form it.

It goes through your pelvis. Then down the back of your thigh. It ends in your lower leg.

Something may press on a nerve root. Like a herniated disc or bone spur (a bony bump).

A tight muscle can also hurt it. The nerve sends pain signals to your brain.

The pain depends on which root is hurt. It also depends on how bad the squeeze is.

A herniated disc happens when a cushion bulges. It can press on a nerve root.

Spinal stenosis means your spine gets narrow. That squeezes your nerves.

Piriformis syndrome happens when a butt muscle spasms. It can irritate your sciatic nerve.

Pregnancy or sitting too long can also cause sciatica. They put pressure on the nerve.

  • Herniated disc: A bulging cushion presses on a nerve.
  • Spinal stenosis: Your spine gets narrow and squeezes nerves.
  • Piriformis syndrome: A butt muscle spasms and hurts the sciatic nerve.
  • Degenerative disc disease: Spine cushions wear out and irritate nerves.

Sciatica vs. Spinal stenosis

Spinal stenosis is a narrowing of the spinal canal that can compress nerves, leading to sciatica. Sciatica is the pain or numbness caused by nerve compression. While spinal stenosis is the structural issue causing it.

Sciatica vs. Piriformis syndrome

Piriformis syndrome involves muscle spasms in the buttocks that irritate the sciatic nerve. Sciatica is the pain or symptoms resulting from this irritation. While piriformis syndrome is the specific muscle-related cause.
