What Causes Sciatica?

Sciatica Assessment & Management

Sciatica is a term commonly used to describe pain, tingling, numbness, or altered sensation that travels along the path of the sciatic nerve—typically from the lower back or buttock down into the leg.

The sciatic nerve is the body’s largest nerve and runs from the lower spine through the pelvis and into the legs.

Sciatica symptoms can occur when the sciatic nerve or associated nerve roots become irritated, compressed, or sensitised for a range of possible reasons.

Common symptoms may include:

• Pain radiating into the buttock or leg
• Tingling or pins and needles
• Numbness
• Burning or altered sensation
• Weakness in the leg or foot in some cases
