Sciatica is nerve pain that runs down the leg, often with numbness or weakness, when a nerve root in the low back is pinched or irritated, most often by a herniated disc. Most of it settles over weeks to a few months without surgery. Surgery for a badly trapped nerve brings the relief forward, but by one to two years the outcome is much the same as waiting.
The nerve-pain drugs people expect to help, pregabalin and gabapentin, do not beat a dummy pill for sciatica. A steroid injection around the nerve gives modest short-term relief, acupuncture is a reasonable adjunct, and a short list of warning signs, above all a change in bladder or bowel control with numbness between the legs, is an emergency that comes first.

What It Is
Sciatica is a symptom, not a diagnosis. It is pain that runs from the low back or buttock down the back or side of one leg, often with tingling, numbness, or weakness, and it comes from a nerve root being pinched or irritated where it leaves the spine. The usual cause is a herniated lumbar disc pressing on the nerve, which is why sciatica is the nerve-related leg pain named apart in the low back pain guide and covered in depth here. The pain follows one nerve's path down the leg, sometimes past the knee, and coughing, sitting, or bending can make it spike.
Most of it gets better on its own. The disc material that presses the nerve tends to shrink and settle over weeks to a few months, and imaging studies show that herniated disc fragments often regress on their own in that time. In one trial of severe sciatica, about 95 in 100 people reported recovery within a year whether they had early surgery or careful non-surgical care, so recovering is the usual course.
Most disc-related sciatica settles on its own over weeks to a few months, and what you do while you wait matters more than any single treatment.
A doctor identifies sciatica mostly from the story and the examination, not from a scan. Raising the straight leg until it reproduces the pain down the leg catches almost every disc herniation, with a pooled sensitivity around 0.92, but it also turns positive in many people who do not have one, so a positive test alone is weak confirmation. The crossed version, where lifting the good leg brings on the pain in the bad one, is the more telling sign, with a specificity around 0.90. An early scan for ordinary sciatica with no warning signs changes little, because disc bulges show up on the scans of pain-free people too, and acting on the image often leads to treatment that does not help.
Two other patterns are worth naming so they are not mistaken for a disc:
- Spinal stenosis. In later life, leg pain more often comes from narrowing of the spinal canal, which builds with standing and walking and eases when you sit or lean forward, rather than from a single disc.
- Pain referred from elsewhere. Not all buttock-and-leg pain is nerve-root pain. Hip trouble and muscle referral can mimic it without following one nerve path or crossing below the knee, and the right label changes what helps.
What Helps
You can speed up recovery, and the options with the best evidence come first: the things you do yourself, then the injections and operations, which add to that base. The graded findings are in the ladder below.
Staying gently active is the foundation. The evidence supports returning to normal movement through the weeks it takes the nerve to settle, with physical therapy that includes directional or graded exercise; resting the leg in bed tends to slow recovery. Because recovery is mostly spontaneous, the aim while you wait is to keep moving, keep comfortable, and protect sleep. Heat gives short-term comfort that makes moving easier, and once the sharp leg pain eases, gradual strengthening supports the back over the longer run.
For severe leg pain that will not settle, an epidural steroid injection around the nerve gives modest short-term relief. Pooling 25 trials in 2,470 people, injections lowered leg pain by about 4.9 points on a 0 to 100 scale over the short term against a placebo injection, an effect that faded over the following weeks, with serious harms uncommon. It is a short-term measure for a bad stretch, and it does not change the disc.
Surgery helps when a badly trapped nerve will not settle, and its value is timing. In a trial of 283 adults with severe sciatica for six to twelve weeks, early microdiscectomy relieved leg pain faster and brought perceived recovery sooner than prolonged conservative care, with recovery arriving at nearly twice the rate (hazard ratio 1.97, 95% CI 1.72 to 2.22). There was no meaningful difference in disability over the first year (P=0.13), and about 95 in 100 in both groups had recovered by one year. A larger trial pointed the same way over two years, with the groups ending up close once many people crossed over between them.
Surgery brings relief forward; it does not produce a better result a year or two later. So it is for severe or persistent leg pain and for progressive nerve signs, while milder sciatica is worth giving time first. Even years out, recovery after surgery is often incomplete: pooling cohorts followed a mean of five years, many people still reported some leg or back pain, much improved from the start but not gone.
Acupuncture is a reasonable adjunct at a modest strength. In a trial of 216 adults with chronic sciatica from a herniated disc, ten sessions over four weeks lowered leg pain by 30.8 mm against 14.9 mm with sham acupuncture on a 100 mm scale, a gap of 16.0 mm that appeared by week two and held through 52 weeks, with better function alongside and no serious harms. Pooled reviews point the same way, though most of the trials behind them are small and of low quality, so the benefit is clear and durable in the best trial and softer across the wider literature.
No single management strategy stands out as the clear winner. A network meta-analysis of 90 randomized or quasi-randomized trials (of 122 studies) spanning surgery, injections, drugs, and conservative care found none clearly superior across outcomes, with much of the underlying evidence of low quality. Recovery is slower for people who start with more intense or longer-lasting leg pain, greater distress, or worse general health; how big the disc bulge looks on a scan matters less than expected.

Pain
Early surgery relieved sciatica faster, but about 95% recovered by one year either way
Operating early makes the leg pain ease sooner, but a year later people who waited and stayed conservative had caught up, with about 95 in 100 recovered either way.
Relief of leg pain and the rate of perceived recovery were faster with early microdiscectomy than with prolonged conservative care (recovery hazard ratio 1.97, 95% CI 1.72 to 2.22). There was no significant overall difference in disability during the first year (P=0.13), and about 95% in both groups reported recovery at one year. Measured in: 283 adults with severe sciatica for 6 to 12 weeks, randomized to early surgery or conservative care with surgery if needed. 39% of the conservative group ended up having surgery within the year, so this compares early surgery with a strategy of delay-then-operate-if-needed, not with avoiding surgery altogether.

Most disc-related sciatica settles on its own over weeks to a few months
In most people, sciatica from a slipped disc gets better on its own over a few weeks to a few months, and the bulge itself often shrinks.
Most sciatica caused by a herniated lumbar disc improves over weeks to a few months as the disc material shrinks and the nerve irritation settles, and imaging studies show that herniated disc fragments often regress spontaneously over that time. Surgery is reserved mainly for severe or persistent cases and for progressive neurological signs. Measured in: Clinical review synthesizing natural history, imaging and management evidence for lumbar disc sciatica. This is a narrative review, so it summarises the field rather than pooling results to a single number, and the pace of recovery varies widely from person to person.
Who this may not transfer to:A narrative review drawing on mixed-sex clinical populations; it does not break natural history down by sex.

Surgery and non-surgical care came out close over two years for disc herniation
When you compare everyone by the treatment they were assigned, surgery and non-surgical care came out close over two years, but so many people switched groups that the head-to-head is hard to read.
Both groups improved substantially over two years. In the intention-to-treat analysis the differences between surgery and non-operative care were small and not statistically significant for the primary outcomes, though very high crossover in both directions blurred the comparison. Measured in: 501 surgical candidates (mean age 42, 42% women) with imaging-confirmed lumbar disc herniation and radiculopathy for at least 6 weeks. Only about half the surgery group had surgery promptly and many in the non-operative group crossed over to surgery, so the intention-to-treat result understates the effect of the operation itself; as-treated analyzes favored surgery.
Who this may not transfer to:42% of participants were women; the primary outcomes were not reported separately by sex.

Many people still had leg or back pain five years after sciatica surgery
Even years after an operation for sciatica, a lot of people still have some leg or back pain and stiffness; it usually gets much better but does not always disappear.
Pooling cohort studies, people who had surgery for sciatica still reported meaningful leg and back pain and disability an average of five years later, with pain scores that had improved from baseline but not resolved. Recovery is real but often incomplete over the long run. Measured in: 39 cohort studies (40 records; 13,883 patients) of people followed up to 5 years after surgery for sciatica. What could explain it instead: Selection by severity. People who come to surgery tend to have started with worse or more stubborn sciatica, so higher residual symptoms may reflect who gets operated on rather than the operation.. These are single-arm cohorts without a comparison group, so they describe long-term status after surgery rather than proving surgery caused the residual symptoms or that non-surgical care would differ.
Who this may not transfer to:The pooled cohorts enrolled both sexes; long-term outcomes were not stratified by sex in the meta-analysis.

Pregabalin did not reduce sciatic leg pain more than placebo (3.7 vs 3.1 on a 10-point scale)
Pregabalin worked no better than a dummy pill for sciatica leg pain, and it caused more side effects such as dizziness.
At 8 weeks the leg-pain intensity score was 3.7 with pregabalin and 3.1 with placebo (adjusted mean difference 0.5, 95% CI -0.2 to 1.2, P=0.19), with no difference at 52 weeks and no benefit on disability or other secondary outcomes. Adverse events, dizziness in particular, were more common with pregabalin. Pain was rated on a 0 to 10 scale. Measured in: 209 adults with moderate-to-severe sciatica, randomized to pregabalin up to 600 mg/day or matching placebo. This tested pregabalin specifically at up to 600 mg/day over 8 weeks; it does not speak to every possible dose or duration, but it is a well-conducted placebo-controlled trial of the standard use.
Who this may not transfer to:Both sexes were enrolled; the trial did not report the primary leg-pain outcome separately by sex.

Gabapentin and related drugs gave no meaningful relief for lumbar radicular pain across nine trials
Reviewing the trials together, drugs like gabapentin and pregabalin did not meaningfully ease this kind of nerve-related back and leg pain, and they raised the risk of side effects.
Across pooled trials, gabapentinoids and other anticonvulsants gave no clinically meaningful reduction in low back or lumbar radicular pain versus placebo, with high-certainty evidence of increased adverse events such as dizziness, fatigue and difficulty concentrating. Measured in: 9 randomized trials of anticonvulsants for chronic low back pain or lumbar radicular pain. The included trials varied in the exact drug, dose and pain definition, and most were of moderate size, so the pooled estimate is more solid for the harms than for ruling out every small benefit.

Epidural steroid injections eased sciatic leg pain modestly in the short term, then faded
A steroid injection around the nerve can take the edge off leg pain for a short while, but the benefit is modest and fades over the following weeks.
Epidural corticosteroid injections produced a small reduction in leg pain and disability in the short term compared with placebo, an effect that was not maintained at longer follow-up. Serious harms were uncommon in the trials. Measured in: 25 randomized trials of epidural corticosteroid injections for lumbosacral radicular pain. The short-term average benefit was small and below what many would call clinically important, and it did not last, so it eases severe pain briefly and is not a lasting fix.
Who this may not transfer to:The pooled trials enrolled both sexes; outcomes were not reported separately by sex.

Acupuncture lowered sciatic leg pain 16 mm more than sham on a 100 mm scale, held to a year
Real acupuncture lowered leg pain and improved movement more than a fake acupuncture control, and the advantage was still there a year later.
At week 4, leg pain on a 100 mm scale fell 30.8 mm with acupuncture versus 14.9 mm with sham (between-group difference -16.0 mm, 95% CI -21.3 to -10.6), and disability improved more with acupuncture (Oswestry difference -8.1 points). The separation appeared by week 2 and persisted through week 52. No serious adverse events occurred. Measured in: 216 adults with chronic sciatica from a herniated disc, randomized to 10 sessions of acupuncture or sham over 4 weeks. This was a single trial conducted in Chinese hospitals with experienced acupuncturists, so the size of the effect may not transfer to every setting, and blinding of a needling sham is imperfect.
Who this may not transfer to:The sample was 68% female and 32% male; the trial did not report the primary outcomes separately by sex.

No single sciatica treatment stood out across 122 trials in a network meta-analysis
When all the treatments for sciatica are compared against each other, none comes out as the clear winner, and a lot of the underlying evidence is shaky.
In a network meta-analysis spanning disc surgery, epidural injection, non-opioid drugs, biological agents and conservative care, no single strategy stood out as clearly superior across outcomes, and much of the evidence base was of low quality with wide uncertainty. Measured in: 122 comparative studies (90 of them randomized or quasi-randomized trials) of treatments for sciatica, analyzed by network meta-analysis. Indirect comparisons across trials that differed in patients, severity and outcome timing carry real uncertainty, so the lack of a standout reflects both actual similarity and weak data.
Who this may not transfer to:The pooled trials enrolled both sexes; the network analysis did not report results separately by sex.

NSAIDs were no more effective than placebo for sciatica pain across ten trials
Across the trials, anti-inflammatory tablets were not clearly better than a dummy pill for sciatica pain, and the evidence itself is weak.
Pooled trials found non-steroidal anti-inflammatory drugs no more effective than placebo for overall pain in sciatica, with only very low to low certainty evidence and small, inconsistent effects on global improvement. Measured in: 10 randomized trials of NSAIDs in people with sciatica. The trials were mostly old and small with a high risk of bias, so this reflects thin evidence rather than a strong finding, and short-term symptom relief for some individuals is not excluded.
Who this may not transfer to:Both sexes were represented across the pooled trials; results were not stratified by sex.

Pooled trials linked acupuncture to greater sciatica pain relief, on small, low-quality studies
Adding up the trials, acupuncture looked helpful for sciatica pain, though the studies behind it are mostly small and low in quality.
Pooling randomized trials, acupuncture was associated with greater pain reduction and higher overall effectiveness for sciatica than control treatments, but most included trials were small and at high risk of bias. Measured in: Randomized trials of acupuncture for sciatica pooled in a systematic review and meta-analysis. The included trials were largely small, single-country and methodologically weak, so the pooled benefit should be read as promising rather than settled.
Who this may not transfer to:The pooled trials enrolled both sexes; results were not stratified by sex.

Measurement And Diagnosis
Worse baseline leg pain and distress, not disc size, predicted slower sciatica recovery
People whose leg pain is more severe or longer-running, or who are more distressed, tend to recover more slowly from sciatica without surgery; how big the disc bulge is matters less than expected.
Across cohort studies, more intense or longer-lasting leg pain at baseline, greater psychological distress and worse general health predicted a poorer recovery from sciatica managed without surgery, while findings for the size of the disc herniation itself were inconsistent. Measured in: 14 original cohorts (reported in 23 articles) of prognostic factors in non-surgically treated sciatica. The primary studies measured different factors in different ways and were of variable quality, so these are consistent signals rather than a validated prediction rule.
Who this may not transfer to:The pooled cohorts enrolled both sexes; prognostic estimates were not reported separately by sex.

The straight-leg-raise test rarely misses a disc herniation but often flags one that is not there
Raising the straight leg to bring on the pain catches almost all disc herniations but also lights up in many people who do not have one; the crossed version, where lifting the good leg reproduces the pain, is the more telling sign.
Pooling diagnostic studies, the straight-leg-raise test had a sensitivity of 0.92 (95% CI 0.87 to 0.95) but a specificity of only 0.28 (95% CI 0.18 to 0.40) for lumbar disc herniation in surgical populations, so a negative test makes a herniation unlikely while a positive one is weak confirmation. The crossed straight-leg-raise test reversed the pattern, with specificity 0.90 (95% CI 0.85 to 0.94) and sensitivity 0.28 (95% CI 0.22 to 0.35). Most other single physical tests performed poorly on their own. Measured in: 16 cohort studies and 3 case-control studies comparing physical-examination tests against imaging or surgical findings for lumbar disc herniation. Most of the studies were done in surgical populations where disc herniation was very common, so the numbers may read differently in primary care, and combining tests performs better than any one alone.
Who this may not transfer to:The pooled studies enrolled both sexes; diagnostic accuracy was not reported separately by sex.

What Does Not Help Much
The medicines most people try first for sciatica are the nerve-pain drugs pregabalin and gabapentin, and they are the ones that help least.
Pregabalin is the clearest case. In the PRECISE trial, 209 adults with sciatica took pregabalin at up to 600 mg a day or a matching dummy pill for eight weeks. Leg pain came out at 3.7 with pregabalin and 3.1 with placebo on a 10-point scale, a difference of half a point that was not significant (95% CI -0.2 to 1.2, P=0.19), with no difference at 52 weeks and none on disability. Side effects, dizziness in particular, were more common on the drug. Pregabalin did not beat placebo for sciatic leg pain and caused more harm.
Gabapentin and the related anticonvulsants fare no better. Pooling nine trials in 859 people, gabapentinoids gave no meaningful reduction in low back or lumbar radicular pain against placebo, with high-certainty evidence that they raised side effects such as dizziness, fatigue, and trouble concentrating. Prescriptions for these drugs climbed for years on thin support, so this is a widely used treatment that the trials now show does not work for this pain.
Anti-inflammatory tablets do little for the leg pain specifically. Across ten trials, NSAIDs were no more effective than placebo for overall sciatica pain, on weak evidence, so while a short course may take the edge off a bad few days for some people, they are not the answer to the radiating leg pain. Long-term opioids carry serious harms with little lasting benefit and are the class to keep away from here.
How It Works
A disc sits between the bones of the spine as a cushion, and when its outer ring tears, the softer inside can bulge out and press on a nerve root nearby. Two things then drive the pain. One is the mechanical squeeze on the nerve; the other, and often the larger, is chemical inflammation, since the disc material triggers an inflammatory response around the nerve that makes it fire and stay irritable. That is why the leg pain can be severe even when the bulge is small, and why the pain follows the exact territory the nerve serves, down the back of the leg for one root, down the side for another.
The reason most sciatica settles without anyone touching the disc is that the body clears the problem on its own. Immune cells move in and gradually resorb the extruded disc material, so the fragment shrinks over weeks to months, and the inflammation around the nerve fades with it. As the chemical irritation eases, the nerve calms and the leg pain lifts, often well before any scan would look normal. This is the mechanism underneath the reassuring natural course, and it is why staying active while the process runs beats waiting in bed for it.
Go Deeper
- Low back pain: the mechanical back pain that sciatica is often confused with, why most improves, and what speeds it.
- Walking and staying active: the free base activity that keeps things moving through the weeks a nerve takes to settle.
- Resistance training: the gradual strengthening that supports the back once the acute leg pain eases.
- Mobility and stretching: the directional and graded movement that sits inside standard non-surgical care.
- Heat and sauna bathing: warmth for short-term comfort that makes moving easier.
- Arthritis and joint pain: where leg or hip pain comes from a joint rather than a nerve, and how the two are told apart.
The Chinese Medicine View
The Chinese Medicine View
Chinese medicine reads sciatica as a Bi syndrome (痹证), an obstruction of qi and blood in the channels that run down the leg, and it locates the problem by which channel the pain follows: down the back of the leg is the Bladder channel, down the side is the Gallbladder channel. That channel map matches where a compressed nerve root sends its pain. The named causes are an invasion of Wind, Cold, and Damp lodging in the channel, or a strain that leaves Blood stagnant, often on a background of Kidney deficiency that leaves the low back and legs poorly supported. Read the patterns below as an interpretive lens on how a person presents, not as a reading of the disc or the nerve, which are seen on a scan. The tradition does more than unblock: where the root is a deep Kidney and Liver deficiency the direction is to tonify and nourish rather than to disperse, and forceful moving techniques on a depleted, older person are held back. Acupuncture for sciatica sits at emerging-to-moderate strength in the trials, and that strength is a measure of the evidence, not an endorsement over the medical care the red flags call for.
Leg pain that is heavy, cold, and stiff, worse in cold or damp weather and better for warmth, following the Bladder or Gallbladder line down the leg. The direction is to warm the channel, dispel cold and damp, and get qi and blood moving, with moxibustion often leading.
Sharp, fixed, stabbing leg pain, often after a lift or injury, worse with pressure, sometimes with numbness where the flow is blocked. The direction is to move Blood, break the stasis, and free the channel.
A duller, weaker ache down the leg with a sore low back and knees, worse with tiredness and better with rest, common in older or long-standing cases. The Kidneys govern the bones and the Liver the sinews, so the direction is to tonify both and nourish the sinews rather than to disperse.
Cautions
Extra restraintEverything to be aware of is here, in one place. This practice suits most healthy people; a few situations call for real care.
The nerve-pain drugs that do not work here
Pregabalin and gabapentin are widely prescribed for sciatica, and the trials show they do not beat a dummy pill for the leg pain while adding dizziness, fatigue, and trouble concentrating. If you have been started on one and it is not helping, raise it with the prescriber before pushing the dose higher, and never stop suddenly on your own, since these are tapered rather than dropped.
Anti-inflammatory tablets over the long haul
A short course of ibuprofen or naproxen for a bad stretch is reasonable for most people. Taken daily for weeks or months, oral NSAIDs raise the risk of stomach bleeding, and over time of kidney and heart problems, and that risk climbs with age and with other heart or kidney conditions. For the leg pain specifically they do little, so leaning on movement and time makes more sense than a daily habit of tablets.
Give it time before an injection or operation
Because most disc-related sciatica settles on its own over weeks to a few months, the usual order is active, non-surgical care first, with an epidural steroid injection or surgery considered when severe leg pain will not settle after six to eight weeks or when nerve signs are progressing. The warning signs below are the exception that overrides waiting.
Sourcing Chinese herbs safely
If you use Chinese herbal formulas for the channel pattern, buy from regulated suppliers and qualified practitioners who test their material. Species substitution is a known hazard in the herb trade, and some warming formulas for cold, painful Bi contain aconite, which is safe only when correctly prepared and dosed by a trained herbalist rather than self-prescribed.
Most sciatica is safe to stay active with and settles with time and movement. Start gently, and consult a licensed practitioner if you have questions, or promptly if any of the warning signs below fit you.
When to See Someone
Most sciatica is not dangerous and settles with time and movement. A short list of situations is different, and one sits above the rest: new bladder or bowel trouble with numbness between the legs can mean the nerves at the base of the spine are being crushed, and that is an emergency measured in hours. See someone the same day, or urgently for the first two, if you have:
- New trouble passing or controlling urine, loss of bladder or bowel control, or numbness around the groin, buttocks, or inner thighs (a saddle pattern), which can mean cauda equina compression and needs surgery within hours to avoid lasting damage(seek urgent care)
- Weakness in the leg or foot that is clearly getting worse, such as a foot that drops or a leg that gives way, which points to a nerve under enough pressure to need prompt assessment(seek urgent care)
- Fever alongside the back and leg pain, or feeling generally unwell, which can signal an infection around the spine
- Sciatica after a significant fall or accident, or in someone with thinning bones or a history of cancer, where a fracture or another cause needs ruling out
- Severe leg pain that is not settling after six to eight weeks of active, non-surgical care, which is the point at which an injection or surgery is usually worth discussing
- Pain that wakes you every night and does not ease with any change of position, or unexplained weight loss, which are worth flagging rather than waiting out
None of this is meant to alarm you. Sciatica is one of the conditions where time and steady movement do most of the work, and the great majority of people recover without surgery. The one sign to act on fast is a change in bladder or bowel control with numbness between the legs.
Common Questions
How long does sciatica take to go away?
Usually weeks to a few months. Most sciatica comes from a herniated disc, and the disc material that presses the nerve tends to shrink on its own while the inflammation around the nerve settles, so the leg pain fades with it. In one trial of severe sciatica, about 95 in 100 people had recovered by a year whether or not they had surgery, so the strong default is that it resolves. Staying gently active while you wait beats resting the leg in bed (Peul, NEJM 2007; Ropper, NEJM 2015).
Do gabapentin and pregabalin work for sciatica?
The trials say no. In the PRECISE trial, pregabalin came out at 3.7 against 3.1 for placebo on a 10-point leg-pain scale, half a point apart and not significant, with more dizziness on the drug (Mathieson, NEJM 2017). Pooling nine trials, gabapentinoids gave no meaningful reduction in this nerve-related back and leg pain and raised side effects on high-certainty evidence (Enke, CMAJ 2018). They are widely prescribed for sciatica, and this is one of the clearer mismatches between how often a drug is used and what it does.
Should I have surgery for sciatica?
For most people, not right away. Surgery relieves the leg pain faster than waiting, and the one-to-two-year result is much the same, so it brings relief forward without changing where you end up. In a trial of severe sciatica, early microdiscectomy sped up recovery (recovery rate nearly doubled) yet about 95 in 100 had recovered at one year in both the surgery and the conservative groups (Peul, NEJM 2007; Weinstein, JAMA 2006). Surgery is for severe or persistent leg pain and for progressive nerve signs, and the red flags below are the situations that need it urgently.
Does acupuncture help sciatica?
At a modest strength, yes. In a trial of 216 people with chronic sciatica from a herniated disc, acupuncture lowered leg pain by 16.0 mm more than sham acupuncture on a 100 mm scale, and the gap held for a year, with better function and no serious harms (Tu, JAMA Intern Med 2024). Pooled reviews agree that it helps, though most of the trials behind them are small and of low quality, so it is a reasonable adjunct to staying active, not a stand-alone cure (Zhang, Front Neurosci 2023).
Is a steroid injection worth it?
For a short window, it can be. Pooling 25 trials, an epidural steroid injection around the nerve lowered leg pain by about 4.9 points out of 100 in the short term against a placebo injection, an effect that faded over the following weeks, with serious harms uncommon (Oliveira, Cochrane 2020). It is a short-term measure for severe leg pain that will not settle, which is why it usually comes after active care has been given time.
When is sciatica an emergency?
When the nerves at the base of the spine are threatened. New trouble controlling the bladder or bowel, numbness around the groin or inner thighs, or leg weakness that is clearly getting worse can mean cauda equina compression, which needs surgery within hours to avoid lasting damage.
