Overview
Sciatica is pain that travels along the sciatic nerve, from the lower back through the buttock and down the leg, usually on one side. It most often happens when a slipped disc or bony wear presses on the nerve. The pain can be sharp, burning or electric and may come with tingling or weakness. Most cases ease within a few weeks with movement, pain relief and physiotherapy; only a few with severe nerve pressure need surgery.
Symptoms
- Pain radiating from the lower back into the buttock and leg
- Sharp, burning or shooting pain down one leg
- Tingling or pins and needles in the leg or foot
- Weakness in the affected leg
- Pain worse on sitting, coughing or sneezing
When to see a doctor
See a doctor if leg pain is severe, lasts more than a few weeks, or comes with leg weakness or numbness.
Emergency — call 108 or go to the nearest hospital
- Numbness around the private parts, loss of control over urine or stools, or severe weakness in both legs — go to a hospital immediately
Causes
Pressure on the sciatic nerve, most often from a slipped (herniated) disc, or from age-related narrowing of the spine.
