Sciatica: Your Questions Answered

Sciatica is one of the most common reasons people come to see an osteopath — and also one of the most misunderstood. The good news is that most cases improve with time and the right conservative care. Here’s an honest look at what sciatica actually is, what the evidence says about treatment, and where osteopathy fits in.

What is sciatica, exactly?

Sciatica refers to pain that travels along the path of the sciatic nerve — typically starting in the lower back or buttock and radiating down the back or side of one leg, sometimes as far as the foot. It’s usually caused by irritation or compression of one of the nerve roots in the lower spine, most commonly from a disc bulge or herniation, though other causes (like spinal stenosis or, less commonly, piriformis muscle irritation) can produce a similar pattern. The pain itself is often sharp, burning, or electric-shock-like, and may come with numbness, tingling, or weakness in the leg.

Is sciatica the same as general low back pain?

No — and the distinction matters for treatment. Low back pain stays localised to the back; sciatica specifically involves nerve-related pain travelling into the leg, often below the knee. Someone can have both at once, but “sciatica” specifically points to nerve root involvement, which is why a proper assessment to confirm what’s actually going on is an important first step rather than assuming every bout of back-and-leg pain is the same thing.

What does the evidence say about treating sciatica?

This is a fair question to ask honestly, because the research picture is genuinely mixed rather than a simple “yes, this works.” Clinical guidelines — including NICE guidelines in the UK — recommend manual therapy and exercise as part of a broader care package for low back pain with or without sciatica, generally alongside education and advice to stay active. However, several recent, rigorous systematic reviews and meta-analyses have found the certainty of evidence for individual treatments (including manual therapy specifically) to be low or very low, particularly when manual therapy is looked at in isolation rather than combined with exercise and active rehabilitation. In short: most good-quality evidence supports a combined approach — manual therapy, exercise, education, and staying active — over any single treatment used alone, and the honest picture is “likely helpful as part of a package of care,” not “proven to fix sciatica on its own.”

It’s also worth knowing that most cases of sciatica improve substantially within weeks to a few months regardless of the specific treatment used, which is genuinely reassuring but also makes it harder for research to tease out exactly how much any one treatment adds on top of natural recovery.

So how can an osteopath actually help?

An osteopath’s role typically covers:

• A thorough assessment — confirming your presentation is consistent with sciatica, screening for nerve involvement (reflexes, strength, sensation), and ruling out the small number of presentations that need urgent medical attention (see below).
• Hands-on treatment — joint mobilisation and soft tissue techniques aimed at the lower back, hips, and surrounding muscles, which may ease pain and muscle guarding in the short term.
• Guided exercise and movement advice — including nerve-gliding (neural mobilisation) exercises and graded activity, which current evidence suggests is at least as important as hands-on treatment, if not more so.
• Realistic education — helping you understand that staying appropriately active (rather than prolonged bed rest) generally supports recovery, and what to expect in terms of timeline.
• Appropriate referral — to your GP or for imaging if your presentation doesn’t fit a typical pattern, isn’t improving as expected, or shows any red-flag features.

How long does sciatica usually take to improve?

Many people see meaningful improvement within six to twelve weeks, though this varies considerably depending on the underlying cause and severity. A small proportion of cases take longer or need further medical investigation (such as imaging or specialist referral) if they aren’t settling with conservative care. Your osteopath should be tracking your progress with you and adjusting — or escalating — your care if things aren’t moving in the right direction.

When does sciatica need urgent medical attention rather than hands-on treatment?

This is the single most important thing to know about sciatica. Seek emergency medical care immediately if you experience any of the following, as they can indicate a serious condition called cauda equina syndrome, which requires urgent treatment to prevent permanent damage:

• New or worsening numbness around the saddle area (inner thighs, genitals, or buttocks)
• New difficulty controlling your bladder or bowel (retention, incontinence, or loss of sensation when going to the toilet)
• Numbness, tingling, or weakness affecting both legs
• Sudden, severe weakness in the leg (such as the foot “slapping” when you walk, or difficulty lifting the front of your foot)

These features are uncommon, but they’re a genuine medical emergency — please go directly to an emergency department rather than booking a routine appointment if any of this applies to you.

Should I rest, or keep moving?

Current evidence and guidelines consistently favour staying as active as your pain allows over prolonged bed rest, which has not been shown to speed up recovery and may make things worse. That doesn’t mean pushing through severe pain — it means avoiding the trap of becoming completely sedentary out of fear of aggravating things. Your osteopath can help you find the right balance of activity and guide you on which movements to ease into and which to modify in the short term.

Getting started

If you’re dealing with leg pain that seems to be coming from your back, a thorough assessment is the right place to start — both to confirm what’s going on and to build a plan that reflects what the evidence actually supports: a combination of hands-on care, the right exercise, and realistic expectations about timeline.
