Sciatica: Just the Figures
Sciatica: the whole thing in five minutes, for when you want the numbers and nothing else.
Pain radiating down the leg from compression or irritation of the sciatic nerve.
Key takeaways
- Typical pattern: pain below the knee, often with tingling or numbness
- Most cases: improve over weeks to months without surgery
- Most useful single change: Keep moving within tolerance rather than resting.
- Commonest mistake: Prolonged bed rest.
- See a doctor if any of the signs under "When to speak to a doctor" below apply to you.
The numbers, in one place
| Measure | Figure |
|---|---|
| Typical pattern | pain below the knee, often with tingling or numbness |
| Most cases | improve over weeks to months without surgery |
| Imaging | only if it would change management |
| Neuropathic pain medicines | generally not recommended for sciatica |
In one paragraph
Most cases improve without surgery, and the important skill is recognising the small number that need urgent action.
Worth doing
- Keep moving within tolerance rather than resting
- Ask about a structured exercise programme or physiotherapy
- Use simple analgesia to enable movement
- Expect gradual improvement over weeks
Worth avoiding
- Prolonged bed rest
- Assuming a scan is needed to start treatment
- Ignoring progressive weakness in the leg

When to speak to a doctor
Seek emergency care for numbness around the genitals or back passage, difficulty passing or controlling urine, loss of bowel control, or weakness in both legs. Seek urgent assessment for progressive weakness in one leg, a foot that drags, or sciatica with fever or unexplained weight loss.
Where this comes from
How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarised or generalised beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
