What are the chances my sciatica will get better?
Published recovery figures can sound reassuring, but they do not all measure the same thing. Here is what one UK study actually found, and how I would use that information when discussing your outlook.
Go to A&E immediately if sciatica affects both legs, you develop numbness around your genitals or bottom, new difficulty starting or controlling urine, loss of awareness or control of bowel movements, or severe or worsening weakness or numbness in both legs. These can signal serious pressure on the nerves. Do not wait for a routine appointment. Call 999 if you need an ambulance.
What can a recovery percentage tell me?
A useful statistic tells you who was studied, what counted as improvement and when it was measured. Becoming pain-free, finding daily activities easier and avoiding an operation are different outcomes. A percentage for one cannot answer the others.
This page looks at the evidence behind an outcome figure. For the course of symptoms and practical recovery advice, see how long does sciatica last?
One directly traceable UK finding
The UK ATLAS study recruited 609 people consulting primary care with back-related leg pain, including 452 diagnosed clinically with sciatica. At one year, the researchers reported that 55% met their definition of improvement: at least a 30% reduction in difficulty with everyday activities, measured using the Roland-Morris Disability Questionnaire. The reported proportion was the same in the sciatica subgroup. Read the original ATLAS study.
This is an improvement-in-function figure, not a complete-recovery rate. Only 74% of the original group returned the one-year questionnaire, which adds uncertainty. Participants had symptoms of different durations and received treatment. The study does not establish the chance that a new episode will resolve without treatment.
Why I do not give everyone the same odds
People attending a GP surgery, people referred after months of symptoms and people selected for an operation are different groups. Their results cannot be used interchangeably.
A study can describe what happened to its participants. It cannot, on its own, provide a reliable personal percentage for you. I would use your assessment and progress to discuss the outlook, while being clear about what cannot be predicted.
Keep treatment results separate from recovery rates
A change on a pain score is not the percentage of people who recovered. Nor does an improvement after treatment show how much of that change was caused by the treatment itself.
For treatment-specific evidence, use the existing guides to nerve-root injections and surgery. For an individual discussion, see how I assess and treat sciatica.
