How Long Does Sciatica Last? A Realistic Timeline

The short answer: Most sciatica gets better in a few weeks to a few months, according to the NHS, and it often settles without surgery. Some people take longer: in one UK study of 609 adults, about one in eight had severe leg pain that did not ease over a year. See a GP if it has not improved after a few weeks.

• Most sciatica improves within a few weeks to a few months, but it can last longer and can come back [1].
• There is no fixed timetable. Studies measure "better" in different ways, so the figures you see online vary a lot.
• Staying gently active usually works better than resting in bed [1][8].
• A smaller group have pain that lingers for months or returns [5][6].
• Numbness around your genitals or bottom, or changes to your bladder or bowels, need emergency help.

For most people, sciatica gets better in a few weeks to a few months. The NHS says it usually settles in that time but can last longer, and it can return later [1]. Think of it as a range, not a deadline.

Here is how recovery looked in one small Dutch study of people who saw their GP for sciatica, with what to do at each stage [4]:

That study had only 68 people in the GP-care group, so treat the numbers as a rough guide. The dip from 62% to 56% may reflect symptoms returning for some people.

Why do the figures differ so much? Each study decides what "better" means. Larger UK studies found:

• 609 adults followed for 12 months: 58% had pain that improved to mild, 26% stayed at moderate pain, 13% stayed severe and 3% improved but remained severe [4].
• A separate primary care group: 55% had improved at 12 months, defined as at least a 30% drop in their back disability score [4].
• A BMJ review of sciatica: about 20 to 30% of people with acute sciatica still had problems after one to two years [6].

What this means: most people do get better, but "better" can mean pain that is much milder rather than gone, and a minority have a long road.

Often, yes. Most people with sciatica improve with simple self-care and time, and surgery is kept for severe pain that has not responded to other treatment [2].

A BMJ review found most people with acute sciatica have a favourable outlook, and that first treatment usually stays conservative (exercise, painkillers, physiotherapy) for about 6 to 8 weeks [6]. A Leiden University analysis of 283 people with sciatica cited earlier studies reporting that the radiating leg pain disappears in most cases within 8 weeks of starting [5].

"Going away on its own" does not mean doing nothing. The NHS advises carrying on with normal activities and starting gentle exercise early [1].

Sciatica is often called a "pinched nerve". The NHS describes it as something pressing on or rubbing the sciatic nerve, which runs from your lower back down the back of your leg. The most common cause is a slipped disc, where the cushion between two spine bones bulges out. Other causes include a narrowed spinal canal (spinal stenosis), a spine bone slipping out of position, and back injury [1].

Typical signs are pain, burning, tingling, numbness or weakness in one buttock and leg, sometimes down to the foot. Coughing, sneezing and moving can make it worse. Back pain alone does not usually mean you have sciatica [1].

Honestly, it is hard to predict. Researchers have looked for clues, but the findings conflict.

A systematic review of people with sciatica who did not have surgery (Ashworth and colleagues, 2011) found conflicting results for pain severity, nerve signs, how long symptoms had lasted and scan findings. Age, gender, smoking, previous sciatica and heavy work did not appear to affect outcomes. The authors said psychological factors were rarely studied and called for better research [7].

A different analysis of 283 people with sciatica from a slipped disc found that women recovered more slowly than men (28% had an unsatisfactory result at 12 months, against 11% of men), and that smoking was linked with poorer outcomes [5]. That was a single study looking back at its own data, so do not read your own timeline from it.

Keep moving gently. The NHS says to carry on with normal activities as much as possible, start gentle exercise early, use heat packs on painful areas, and avoid sitting or lying down for long periods. Moving may hurt, but it is "not harmful and can help you get better faster" [1].

Other things that matter:

• Painkillers: ask a pharmacist. The NHS says paracetamol is unlikely to help and it is unclear how much anti-inflammatories such as ibuprofen help [1].
• Physiotherapy: it is free on the NHS across the UK, though waiting times can be long. In many areas you can refer yourself [1][2].
• Bed rest: a Cochrane review found that for sciatica, advice to rest in bed and advice to stay active made little or no difference to pain or function. For back pain without sciatica, staying active gave small benefits [8]. Resting in bed is not shown to speed recovery.
• Sleep: a few small changes can make nights easier. See our guide to how to sleep with sciatica.
• Walking: gentle walking is a good place to start. Our guide to whether you can walk with sciatica covers how far and how fast.

Gentle, controlled movements are a sensible starting point. These three are common first steps. Start small and build up over days [1]:

1. Pelvic tilt. 

Lie on your back with your knees bent. Gently flatten your lower back into the floor, hold for 5 seconds, then relax. Do 8 to 10 repetitions. See our pelvic tilt exercise.

1. Glute bridge. 

Lie on your back with your knees bent. Squeeze your buttocks and lift your hips until your body makes a straight line from shoulders to knees. Hold for 2 to 3 seconds, then lower slowly. Do 8 to 10 repetitions, up to 2 sets. See our glute bridge exercise.

1. Bird-dog. 

On your hands and knees, slowly reach one arm forward and the opposite leg back, keeping your back flat. Hold for 3 to 5 seconds. Do 5 to 8 repetitions each side. See our bird-dog exercise.

Stop if leg pain moves further down your leg, tingling or numbness gets worse, or you feel sharp pain. Try an easier version, or wait a day.

Kai, Loosn's AI physio coach, can help you pace these around your pain from day to day. A written plan works equally well, and neither replaces an assessment if your symptoms are severe, getting worse or unusual.

See a GP if your sciatica has not improved after a few weeks of home treatment, is getting worse, or is stopping you doing everyday activities. In many areas you can also refer yourself to an NHS community musculoskeletal (MSK) service [1].

If pain is severe and has not responded to other treatment, a hospital specialist may consider options such as injections or surgery [2]. Pain that seems stuck is worth raising early. For a wider view of back-pain warning signs, see our guide to when lower back pain is serious.

Call 999 or go to A&E if you have [1][3]:

• sciatica on both sides, or severe or worsening weakness or numbness in both legs
• numbness around or under your genitals, or around your bottom (anus)
• difficulty starting to pee, being unable to pee, or losing control of your bladder, when this is not normal for you
• not noticing when you need to poo, or losing control of your bowels, when this is not normal for you
• back pain that began after a serious accident, such as a car crash

The NHS says not to drive yourself to A&E: ask someone to take you, or call 999 [1].

Call 111 or ask for an urgent GP appointment if you have [3]:

• back pain with feeling hot, cold, shivery or generally unwell
• sudden severe pain, or pain that is getting worse quickly

See a GP promptly if you have [1][3]:

• pain that has not improved after a few weeks of home treatment
• pain that does not improve with rest, or is worse at night
• unexplained weight loss
• leg weakness that is new or getting worse

Loosn is not a substitute for assessment when symptoms are severe, getting worse or unusual.

Can sciatica last for months? 

Yes. The NHS says sciatica usually gets better in a few weeks to a few months, but it can last longer [1]. In a BMJ review, about 20 to 30% of people with acute sciatica still had problems after one to two years [6]. If yours is dragging on, see a GP.

Is it normal for sciatica to last more than 6 weeks? 

It is common enough, but it is worth getting checked. In a small Dutch study, 44% had improved by week 6 and 62% by week 12 [4]. The NHS advises seeing a GP if there is no improvement after a few weeks of home treatment [1].

Does sciatica come back? 

It can. The NHS says sciatica can return after it has gone [1]. In a Leiden University analysis, many people had back or leg pain again after first recovering [5]. Staying active, and getting help early if it returns, are sensible habits.

Should I stay in bed until sciatica goes away? 

No. The NHS advises against sitting or lying down for long periods and says moving is not harmful [1]. A Cochrane review found little or no difference between bed-rest advice and advice to stay active for sciatica [8].

When should I go to A&E for sciatica? 

Go to A&E or call 999 if you have sciatica on both sides, severe or worsening weakness or numbness in both legs, numbness around your genitals or bottom, or trouble controlling your bladder or bowels [1]. Do not drive yourself.
