Pain that travels from your lower back or buttock down into your leg can be worrying, especially when it is sharp, burning or comes with pins and needles. This kind of nerve-related leg pain is often called sciatica, and it is one of the most common reasons people search for help with their back and leg.
There is a lot of mixed advice about sciatica, particularly around whether you should rest, get a scan or push on. Here is what sciatica actually is, what the evidence says helps, the red flags that need urgent care, and when it is worth seeing a physio.

What is sciatica?
Sciatica is pain that travels along the path of the sciatic nerve, from the lower back or buttock down the back of the leg, sometimes past the knee. It is usually a sign that a nerve root in the lower back is being irritated or compressed. Along with the pain, some people notice pins and needles, numbness or a feeling of weakness in the leg.
Sciatica is a description of a pattern of symptoms rather than a diagnosis on its own, so part of a good assessment is working out what is driving it for you.
What causes sciatica?
Sciatica is commonly related to a disc in the lower back pressing on or irritating a nearby nerve root, but it can also come from other age-related changes in the spine. Common contributors include:
- A disc bulge or irritation pressing on a nerve root
- Age-related narrowing around the nerve
- A sudden increase in bending, lifting or sitting load
- A period of reduced activity and deconditioning
It is rarely one single factor, and the amount of pain does not always match what a scan shows.
Should I rest in bed until it settles?
Prolonged bed rest is generally not the answer. While it makes sense to ease off very aggravating activities during a bad flare, staying gently active is usually recommended over lying still. The reassuring news is that most cases of sciatica settle over time.
Surgery versus active care
Even when a disc is involved, trials comparing early surgery with conservative care have found that surgery can speed up short-term relief, but there is no meaningful difference in outcomes at one and two years.
That is why a non-surgical, active approach is a sound starting point for most people.
What actually helps sciatica?
The evidence favours staying active and following a graded plan rather than resting and waiting. A typical approach includes:
- Keeping gently active within comfortable limits
- Movements and exercises that ease your symptoms and settle the nerve
- Gradually building back your tolerance for sitting, bending and lifting
- Guidance on pain, and reassurance about what the symptoms do and do not mean
Many people improve with a structured plan tailored to their symptoms and goals, and a physio can help you judge what to push and what to ease.
How long does sciatica take to settle?
Sciatica often eases over a period of weeks to a few months, though timelines vary from person to person. Sticking with a sensible, gradually progressing plan usually matters more than chasing a quick fix or an early scan. A physio can help you track progress and adjust the plan as your symptoms change.
Red flags: when to get urgent help
Most sciatica is not dangerous, but a small number of symptoms need urgent medical attention. Seek emergency care if you develop:
- Numbness around the groin, buttocks or inner thighs (a saddle pattern)
- Loss of control of your bladder or bowels, or difficulty passing urine
- Severe or rapidly worsening weakness in one or both legs
These can be signs of a serious problem that needs prompt assessment, so do not wait to see if they settle.
When should you see a physio?
See a physio if your sciatica is limiting your work, sleep or daily life, is not settling, or you want a clear plan to recover with confidence. Getting assessed early can help you understand what is driving your symptoms, rule out anything concerning, and start an active plan sooner.
