About this condition

Sciatica is pain that travels from the lower back or buttock down the back of the leg, sometimes into the foot. It happens when a nerve root in the lower spine is irritated or compressed, often by a slipped (herniated) disc.

Most cases improve with time and non-surgical treatment, but persistent or severe symptoms need assessment.

Common symptoms

  • Pain from the buttock down the back of the leg
  • Numbness or tingling in the leg or foot
  • Weakness in the leg
  • Pain that gets worse with sitting, coughing or bending

Having one or more of these does not by itself mean you have a particular condition. A doctor's assessment is needed to find the cause.

How it is assessed

  1. A history and examination of the spine and legs.
  2. A review of any previous scans.
  3. An MRI scan if the doctor advises it.

Who may be affected

  • People with leg pain that is not improving
  • People with numbness or weakness in the leg

Preparing for your appointment

It helps to bring:

  • Previous medical reports, prescriptions and hospital discharge summaries
  • MRI or CT scan films and reports, if you have them
  • A list of all the medicines you take, with their doses
  • A short note of your symptoms: when they started, how often they happen and what makes them better or worse

Frequently asked questions

Does sciatica need surgery?

Most people improve without surgery. Surgery may be considered when symptoms are severe or persistent, or cause significant weakness.

Should I stay in bed?

Long periods of bed rest are usually not helpful. Gentle activity within your comfort limits is generally encouraged.
