Your doctor or physiotherapist has diagnosed you with ‘sciatica’ and told you that it usually settles within six weeks. Six weeks have come and gone, your leg is still sore, and you're starting to wonder whether something is seriously wrong - and what the next step might be.
It is true that most sciatica improves without any procedure, even when it hurts a great deal and even when a scan looks alarming.
This article walks through the main treatment options, so you can see where you are, what the evidence says about each one, and what a sensible next move might be. In practice, these options are often combined or used in parallel rather than one after another.
What sciatica is and isn't
Sciatica is a word that describes a symptom; it is not a diagnosis.
It simply means pain travelling from the lower back or buttock into the leg. In everyday language, almost any leg pain gets called sciatica, and almost any sciatica gets blamed on a “slipped disc” that supposedly needs surgery. Neither assumption holds up. (Discs, incidentally, don't slip!) Researchers now recommend avoiding the word “sciatica” without further explanation and instead using “spine-related leg pain” (and this is what we will call it in the rest of this article) as an umbrella term, because three quite different things hide beneath it:
|
|
Somatic referred pain |
Radicular pain |
Radiculopathy |
|
What is happening |
Muscles, joints or discs in the back or buttock send confusing signals. No nerve injury. |
An irritated, inflamed nerve root fires danger signals. |
A nerve root is not conducting properly: may indicate a loss of nerve function. |
|
What it feels like |
Dull, deep, aching, hard to pinpoint. |
Sharp, shooting, electric or burning, in a narrow line down the leg. |
Numbness, weakness or reduced reflexes. Pain is not always present. |
|
Where |
Buttock and thigh, usually above the knee. Rises and falls with back pain. |
Often below the knee, into the foot or toes. |
In the skin and muscles supplied by that specific nerve. |
Muscle tightness in the gluteal muscles, hamstrings or deep hip muscles typically produces somatic referred pain: real and sometimes severe, but not necessarily a sign of a nerve problem. A related group of symptoms involves the sciatic nerve being squeezed outside the spine, in the buttock (known as piriformis or deep gluteal syndrome).
Radicular pain is most often caused by a lumbar disc herniation irritating a nerve root, and it is often the inflammation around the nerve, rather than compression alone, that drives the pain.
Radiculopathy is different again: it is about lost nerve function, not pain, and it is the category that can occasionally need surgery sooner.
This distinction is important, as it influences treatment options.
Referred and muscle-related pain responds to movement, lifestyle changes, graded loading, and time. Minimally invasive procedures might also help.
Radicular pain follows the favourable natural course described below and minimally invasive procedures may help ease pain while recovery takes place.
Only true radiculopathy with a significant deficit, or the presence of red flags, may shift the conversation towards surgery. Our guide on how to know if it's nerve pain and not muscle pain can help you tell them apart.
Red flags that need urgent care
|
Go to an emergency unit the same day if you have: l New difficulty passing urine, loss of bladder or bowel control, or reduced sensation when you pass urine or wipe l Numbness around the genitals, buttocks or inner thighs (the “saddle” area) l Severe or progressive weakness in a leg, such as a foot that drags or gives way l New numbness or weakness on both sides l New back and leg pain with fever, unexplained weight loss, a history of cancer, significant recent trauma, or a weakened immune system These can signal cauda equina syndrome or another serious underlying condition. They are uncommon, but they are time-critical, so please do not wait for a routine appointment. |
How long does spine-related leg pain usually take to settle?
Reassuringly, spine-related leg pain is usually self-limiting. In a landmark Dutch trial of people who still had severe spine-related leg pain after 6–12 weeks, about 95% had recovered by one year whether they had early surgery or prolonged conservative care, and 61% of those assigned to conservative care never needed an operation. A more recent UK primary-care trial found a median recovery time of around 10–12 weeks. Expect gradual improvement over weeks to a few months, not days.
Even if a disc herniation is present and causing nerve root irritation, the disc itself tends to shrink if it is left alone. A 2023 meta-analysis found that herniated disc material regressed on follow-up scans in about 13% of bulges, 53% of protrusions, 70% of extrusions and 93% of sequestrated fragments. Counter-intuitively, the “worse-looking” discs are often the ones that resolve most!
Three myths worth retiring: that every leg pain is ‘sciatica’, that a “slipped disc” never heals, and that a disc bulge on your scan means you need an operation.
So what does “not improving” look like? Pain that hasn't meaningfully eased after about six weeks of active self-care, is getting worse, is stopping you sleeping or working despite appropriate care, or comes with new weakness or numbness. That is the point at which you should consider a comprehensive assessment – there is still no reason to panic.
What you can do yourself
l Stay active within tolerance. Short, frequent walks beat bed rest. Bed rest does not speed recovery. It is important to continue with normal activities as pain allows.
l Use heat and positioning. Heat can ease muscle spasm, and lying on your side with a pillow between your knees, or on your back with knees supported, often eases leg pain. See our best stretches for sciatica and how to sleep with sciatica.
l Pace yourself. Increase activity gradually and avoid pushing into a flare. Setbacks along the way are normal and do not mean damage or that you should stop.
Adjusting your daily activities while you wait
Still having pain at six weeks is common and does not mean something has gone wrong. During the waiting period, the aim is to adjust your daily activities, not to stop them.
Break tasks into shorter bursts and change position often: if you sit for work or driving, stand up or walk every 20 to 30 minutes and use a supportive chair with your feet flat.
When lifting, keep the load close, bend at the hips and knees, and share or trolley heavy items, though there is no need to avoid bending altogether.
Spread household chores across the day, sit for tasks like food preparation where you can, and consider asking your employer for temporary modified duties or more frequent breaks.
These changes are temporary: as your pain settles, build back towards your usual routine gradually, and if you have a flare, scale activities down rather than stopping completely.
Physiotherapy
If movement is limited or pain hasn't eased after a couple of weeks, a physiotherapist is a sensible next call. In the acute phase they target pain-easing positions and movement, nerve mobility, contributing muscle and joint stiffness, and education about what is safe.
Graded loading is generally recommended over rest for nerve-related pain because a sensitised nervous system tends to settle when it is reintroduced to movement gradually, which we explain in why movement is medicine for the nervous system.
Pain science education and psychological well-being
Understanding how pain works is a treatment in its own right.
Pain is a protective signal shaped by the nervous system, and it is influenced by stress, sleep, mood and what we believe is happening in our bodies, not simply by how much tissue is irritated. Knowing that disc herniations are common, often shrink, and rarely signal lasting damage can reduce fear and the urge to avoid movement, which makes it easier to stay active and recover.
Our pain science education programme explains this in practical terms.
Psychological well-being matters too. Worry, low mood, poor sleep and ongoing stress can turn up the “volume” of pain and make recovery feel slower, while pain that disrupts sleep, work and relationships can in turn affect mood. Protecting your sleep, building in relaxation or breathing practices, staying connected to family and friends, and asking for support if you feel anxious or low are all part of treatment, not a sign of weakness or that the pain is “in your head”.
A psychologist or Occupational Therapist can help with pain-focused strategies where needed; see how chronic pain impacts mental health for more.
Medication options
Medication can make the weeks more bearable, but it supports recovery; it does not fix the nerve itself. The evidence is also less generous than many people expect.
l Simple analgesia and anti-inflammatories: evidence specific to spine-related leg pain is limited, though short courses at the lowest effective dose can help comfort. It is important to speak to your doctor to find out if taking these medications are safe for you.
l Nerve pain medication: it seems logical, but in the PRECISE trial of 209 people, nerve pain specific medication (pregabalin) was no better than placebo for spine-related leg pain at eight weeks or one year, and caused more side effects such as dizziness. NICE guidance advises against this type of medication for spine-related leg pain.
l Oral steroids: a large placebo-controlled trial found they did not improve leg pain, and guidelines advise against routine use, although a doctor may occasionally consider them on a case by case basis.
l Opioids: not recommended for chronic spine-related leg pain.
If you already take any of these, don't stop suddenly; speak to your doctor first.
When is a scan actually useful?
Early imaging rarely changes management, because the first weeks of treatment are the same whatever the scan shows. An MRI matters when there are red flags, a significant or progressive neurological deficit, or persistent pain despite a proper conservative programme and you are considering an injection or surgery, so the findings can be matched to the right nerve level.
Be wary of scan reports. In people with no pain at all, disc bulges appear in about 30% of 20-year-olds and 84% of 80-year-olds, and disc protrusions in 29% to 43%. A finding only matters if it matches your symptoms and examination, as we explain in why normal MRI results don't always mean you're pain-free. The reverse is also true: an alarming scan does not automatically mean an alarming outcome.
Epidural steroid injections and selective nerve root blocks
An epidural steroid injection places steroids, usually with local anaesthetic, in the space around the irritated nerve root under imaging guidance, to calm local inflammation. People with clear radicular pain that matches their imaging, and pain severe enough to block rehabilitation, tend to respond best.
Relief from an epidural injection is often temporary, lasting from several weeks to a few months. It works best as a window of lower pain in which to do your rehabilitation while natural recovery continues, rather than as a stand-alone cure.
Most people go home the same day and resume gentle activity within a day or two. Temporary soreness, flushing, and a short rise in blood sugar in people with diabetes are the common effects; serious complications such as infection, bleeding or nerve injury are rare. Tell your doctor if you take blood thinners.
A selective nerve root block is a similar procedure that places a small amount of local anaesthetic, sometimes with steroid, beside one specific nerve root. Read more about the nerve block procedure.
Pulsed radiofrequency and other options
Pulsed radiofrequency delivers short pulses of energy near the dorsal root ganglion, the nerve's sensory relay, at temperatures that do not burn or destroy tissue (below about 42 °C), with the aim of modulating pain signalling. It is considered for persistent radicular pain that hasn't settled with conservative management and injections, and should always be accompanied by a well designed multi-modal rehabilitation plan.
Pulsed radiofrequency can be a useful option for carefully selected people. Learn more in pulsed radiofrequency neuromodulation.
Other interventional options exist, but their evidence is limited. Selection depends on your individual clinical picture, and it's reasonable to ask your doctor what the evidence is for any procedure you're offered.
When is surgery the right call?
Surgery, usually a microdiscectomy, is appropriate in three situations: persistent, disabling pain despite a complete conservative programme with imaging that matches your symptoms; significant or progressive neurological deficit, such as a dropping foot; and cauda equina syndrome, which is an emergency.
Surgery addresses the compression, not a sensitised nervous system, and although leg pain often eases more quickly than with non-surgical care, back pain may remain. It is likely that you would still have to engage in other multimodal rehabilitation to achieve the best outcomes after your operation.
For the bigger picture, read why spinal surgery isn't always the solution for back pain.
What if the pain persists after treatment?
A minority of people have pain that lingers after the compression has been treated or has settled. This can reflect persistent neuropathic pain, often involving a sensitised nervous system, a process we describe in central sensitisation. After an operation it can overlap with post-surgical chronic pain.
A normal post-operative scan with persistent pain does not mean your pain isn’t real; the pain can come from a sensitised nervous system rather than ongoing compression. Importantly, further options remain, including carefully chosen medication, nerve-focused procedures, graded rehabilitation, pain education and psychological support within a multidisciplinary programme.
Finding the right next step for your spine-related leg pain
Treatment options include self-care and movement, physiotherapy and biokinetics, carefully chosen medication, injections and blocks, and, only sometimes, surgery. They are often combined or used in parallel, not one after another. The principle is to identify the right treatment for the right patient at the right time, and for that you might need the guidance of a clinician.
