Back Pain Doctor
Sciatica
Sciatica, more precisely called lumbar radicular pain, occurs when a nerve root in the lower spine is irritated or compressed — often by a disc bulge or age-related narrowing. The hallmark is leg pain that follows the path of the nerve, sometimes with altered sensation or weakness.
The good news is that most episodes of sciatica improve with time and conservative management, including staying as active as your symptoms allow, physiotherapy, and pain management. Recovery is often gradual rather than sudden.
We assess the pattern of your symptoms, check for any features that require further investigation or referral, and help you with a management plan. Where appropriate, we discuss options for pain control while the nerve settles, and we are clear about when a surgical opinion is and is not warranted.
Common symptoms
- Pain radiating from the back or buttock down the back or side of the leg
- Pins and needles, numbness or a burning sensation in the leg or foot
- Leg pain that may be worse than the back pain itself
- Symptoms aggravated by sitting, bending or coughing

Evidence for twelve treatment options in sciatica
This is not a fixed ladder or a package of treatments. Every option is assessed independently against this diagnosis, including treatments with limited direct research that may still be reasonable for a clearly defined tissue target. The evidence level, likely benefit, risks, cost and alternatives are weighed at consultation.
Foundation — diagnosis, education and rehabilitation
The part of care with the broadest relevance. For many people it is enough on its own; other options are judged against it, not automatically added after it.
Diagnosis, education and progressive rehabilitation Working out what is driving the pain, explaining what your imaging does and does not mean, and building a graded loading plan you can actually follow. Core care
What it involves
Assessment to identify the likely pain source, an explanation of what the diagnosis means, adjustment of the loads that aggravate it, and a progressive strength and conditioning plan — with weight management where that is clinically relevant.
What the evidence shows
Every high-quality guideline says the same thing. The American College of Physicians makes a strong recommendation that chronic low back pain be treated first with exercise and multidisciplinary rehabilitation rather than drugs or procedures (Qaseem, Ann Intern Med 2017). An overview of 15 primary-care guidelines found consistent agreement on education, staying active, exercise and reassurance, and on discouraging routine imaging (Oliveira, Eur Spine J 2018). For neck pain the strongest effects also belong to exercise, with strengthening of the neck and upper quadrant showing a moderate short-term effect (Sterling, J Clin Med 2019). Adding pain-science education to exercise improves pain, disability and fear of movement over exercise alone (Bonatesta, J Pain 2021).

Where it fits for you
Understanding why the back hurts, and moving well, does more than anything injected. Imaging is used to answer a specific question, not as a starting point — degenerative findings are near universal and frequently unrelated to the pain.
Muscle and symptom-modifying options
Useful only when the examination identifies the tissue they target or when short-term pain control creates a useful rehabilitation window.
Wet needling and trigger point injection (trigger point injection) A fine needle into a tender band of muscle, with a small volume of dilute glucose solution injected through it. Worth discussing
What it involves
The needle is placed into the tender muscle band and a small volume of 5% glucose with 0.02-0.08% lignocaine is injected. Often done in the same visit as your assessment, and usable where the tender area sits deeper. Dry needling — the same technique with nothing injected — is not offered here.
What the evidence shows
The evidence sits in the muscular mimic rather than in nerve root pain. Deep gluteal syndrome — the piriformis and its neighbours irritating the sciatic nerve — is a recognised non-discogenic cause of sciatica-like pain (Park, Bone Joint J 2020), and a double-blind randomised comparison of 84 people found ultrasound-guided lignocaine into the piriformis reduced pain and disability significantly at one month, though botulinum toxin outlasted it by six (Elsawy, Healthcare 2022). We found no trial of needling or injection into muscle for sciatica caused by a disc.
Pairing reviewed 2026-09-07.
Where it fits for you
Considered where examination points to gluteal or piriformis muscle reproducing the leg pain, rather than a nerve root. If the leg pain is truly radicular, this is not the treatment for it and we will say so.
Ultrasound-guided injections Guidance means we can see the needle reach the target. What goes into the needle depends on the diagnosis. Small, short-term effect
What it involves
The injection is performed under ultrasound so the needle can be watched into the target structure. What is injected is decided by the diagnosis — and corticosteroid is used sparingly, for the reasons set out below.
What the evidence shows
The trials in sciatica test an epidural corticosteroid injection placed under X-ray or CT, which is a different procedure from the ultrasound-guided soft-tissue injections done here. Pooling 25 placebo-controlled randomised trials in 2,470 people, epidural corticosteroid was probably better than a placebo injection for leg pain in the short term, but the difference was small — 4.9 points on a 0 to 100 scale (95% CI -8.8 to -1.1) — with a similar sized effect on disability (-4.2, -6.0 to -2.2) and moderate-quality evidence at best (Oliveira, Spine 2020). The American Academy of Neurology review of 90 randomised trials found the same shape of answer for radicular pain: probably better short-term pain, roughly one extra person helped for every four treated, and not enough evidence to say anything about pain at six months or beyond (Armon, Neurology 2025). A reanalysis of the same trial set, restricted to those done under X-ray guidance, argues the evidence is considerably stronger than that (Manchikanti, Pain Physician 2022), so the size of the benefit is genuinely disputed rather than settled.
Pairing reviewed 2026-09-17.
Where it fits for you
Not a procedure performed here. An epidural injection is done under X-ray or CT by a radiologist or a pain medicine specialist, so this is a referral conversation rather than something we provide. Worth raising where leg pain has not settled with loading and education and is limiting what you can do, with the expectation set at some weeks of partial relief rather than a cure. New or progressive weakness, numbness or bladder change needs assessment, not an injection. See the note on cortisone.
V-ACTOR vibration therapy (vibration therapy) Low-frequency vibration applied over tender muscle. Not a shockwave, despite sharing the machine. Plausible — no studies
What it involves
A vibration handpiece is moved over the tender muscle and fascia for a few minutes. It runs from the same STORZ MASTERPULS icon console as radial shockwave but is a separate handpiece delivering a different, gentler form of energy. No needles, no anaesthetic, no downtime.
What the evidence shows
No published clinical trial of this device in this condition. It is a vibration handpiece delivered from the same console as radial shockwave, and the rationale is myofascial rather than tendon- or bone-directed.
Pairing reviewed 2026-08-30.
Where it fits for you
A comfort measure used within a session where muscular tightness is limiting movement. Never the reason for the appointment, and not a substitute for the treatments that do have evidence.
Energy-based treatment options
Radial pressure wave, focused shockwave and EMTT have different targets and different evidence. They are assessed separately rather than treated as one category.
Radial or focused shockwave? Read the overviewRadial shockwave (radial pressure wave) Broad treatment across tender muscle and fascia, close to the surface. Not for a disc problem
What it involves
A handpiece is moved over the tender tissue while ballistic pressure pulses are delivered, using a transmitter head chosen for the tissue — including heads shaped for fascia and for the muscle either side of the spine. The pulse is strongest at the skin and weakens with depth, so this is mainly a myofascial treatment, though it can reach deeper in some areas. No anaesthetic, no downtime, usually a course of sessions about a week apart.
What the evidence shows
A tested absence for the nerve-root part of this problem, and a real trial for the muscular part. A search pairing lumbar disc herniation, disc herniation, sciatica and radiculopathy with shockwave, shock wave and ESWT returned nine records and not one trial of shockwave for disc-related nerve-root pain. Where sciatic-type pain is coming from the deep gluteal muscles it is a different story: 48 people with piriformis syndrome were randomised to ultrasound-guided shockwave or ultrasound-guided dry needling, both groups also stretching, and both improved pain, Oswestry disability and lower-limb function at one and three months with no difference between them (Dede, Turk J Phys Med Rehabil 2026). Shockwave also appears in a surgical series as part of the conservative care that had failed before piriformis release (Han, Clin Orthop Surg 2017).
Pairing reviewed 2026-09-13.
Where it fits for you
Considered where the leg pain is being driven by tender gluteal muscle rather than by a disc pressing on a nerve root. It does nothing for a disc or a nerve root, and new or progressive weakness or numbness needs assessment rather than treatment.
Focused shockwave (ESWT) A true shock wave converging at depth — for tendon, joint, ligament and bone. Only if relevant
What it involves
A focused system generates an acoustic shock wave that converges at a focal point set at a defined depth, concentrating the energy where the target is. This is the form we use for tendon, joint, ligament and bone. Typically four to six sessions about a week apart, no anaesthetic and no formal downtime.
What the evidence shows
Focused shockwave is not aimed at a disc, a facet joint or a nerve root, and there is no trial evidence for it in these conditions.
Pairing reviewed 2026-08-30.
Where it fits for you
Considered only where examination finds a separate tender muscle or tendon contributing to the pain.
EMTT (magnetotransduction therapy) High-energy magnetic pulses applied over the area. Painless, no contact. Plausible — no studies
What it involves
You sit with the applicator positioned over the area for a short session. Painless, no gel or contact required, and usually delivered as a course — commonly alongside shockwave.
What the evidence shows
There are no published randomised trials of EMTT in this condition, or in any musculoskeletal condition, that we can point to. The supporting work is laboratory work: EMTT increased tenocyte proliferation, migration and collagen expression in cultured human tendon cells (Mancini, Int J Mol Sci 2025). The nearest human evidence for a related electromagnetic therapy is negative — a randomised trial of pulsed electromagnetic field therapy added to eccentric exercise for Achilles tendinopathy found no improvement in outcome scores or tendon neovascularity over eccentric exercise alone (Ko, Orthop J Sports Med 2024).
Pairing reviewed 2026-08-30.
Where it fits for you
Offered only as an adjunct alongside treatment that does have evidence, never as the plan itself, and only after that gap is explained. Much of the EMTT literature is manufacturer-affiliated, which is part of why we describe it this way.
Biologic and joint injection options
Each injection is assessed independently for the named diagnosis. Cost, uncertainty, likely benefit, risks and alternatives are part of the decision.
Platelet-rich plasma (PRP) Your own blood, concentrated and injected under ultrasound guidance. Evidence mixed
What it involves
Blood is taken from your arm, spun to concentrate the platelets, and injected into the target under ultrasound guidance in the same appointment.
What the evidence shows
The trials here are of platelet-rich plasma given as an epidural or transforaminal injection around the nerve root — a different procedure from the soft-tissue injections done in this clinic. Two 2025 meta-analyses reach different conclusions. Pooling five randomised trials in 310 patients, epidural platelet-rich plasma matched epidural steroid for pain (weighted mean difference −0.09 on the 0–10 scale, 95% CI −0.66 to 0.47) and for disability, without extra adverse events (Muthu, Exp Biol Med 2025). Pooling seven studies in 416 patients, steroid was better for disability at four weeks (standardised mean difference 0.48, 95% CI 0.20 to 0.75), with no difference at any later point (Wang, J Orthop Surg Res 2025). A systematic review graded the certainty of the whole body of work very low (Kubrova, Biomedicines 2022).
Pairing reviewed 2026-09-03.
Where it fits for you
Not a treatment offered here, and not a substitute for the loading and education that carry the evidence in sciatica. Where leg pain has not settled, this is a referral conversation about an image-guided epidural procedure — performed under CT by a radiologist, or by a pain medicine specialist — rather than something we provide.
Prolotherapy (dextrose) A course of dextrose injections into and around the structure and its attachments. Evidence mixed
What it involves
Hypertonic dextrose is injected at the tender ligament and tendon attachments, and into the joint where relevant, usually as a series of treatments a few weeks apart.
What the evidence shows
The evidence in nerve-related leg pain conflicts. A systematic review of dextrose prolotherapy in chronic spinal pain reported rapid relief from low-concentration epidural dextrose in radicular pain (Nazwar, J Anaesthesiol Clin Pharmacol 2026), but the single randomised trial of epidural prolotherapy showed no benefit past forty-eight hours (Desai, Pain Practice 2020) and an American Pain Society review found prolotherapy not effective for low back and radicular pain (Chou, Spine 2009). Reports of sciatic pain arising outside the spine and settling with prolotherapy are single cases (Yoon, Life 2025).
Pairing reviewed 2026-09-05.
Where it fits for you
Not a treatment for a compressed nerve root. Considered only where the leg pain is being driven by an irritable ligament or attachment rather than the root itself, and after core care has had a fair trial.
Viscosupplementation (hyaluronic acid) A gel-like injection into an arthritic joint. Widely used, and genuinely contested. Not used here
What it involves
One or a short series of hyaluronic acid injections into the joint under ultrasound guidance.
What the evidence shows
Hyaluronic acid appears in the sciatica literature as an additive to a nerve root block, not as a joint injection. In 44 people with lumbar radiculopathy, adding a sodium hyaluronate and carboxymethylcellulose solution to a cortisone nerve root block reduced the flare of pain that often follows the procedure — 2.4 against 4.2 out of 10 at two weeks — but made no difference by six weeks and no difference to function at six or twelve weeks (Ko, Spine J 2018). That is an injection around a nerve, which belongs to the guided-injection row. Nothing has tested a spinal joint injection of hyaluronic acid for sciatica.
Pairing reviewed 2026-09-20.
Where it fits for you
Not offered for this problem. Sciatica comes from an irritated nerve root rather than from a dry joint.
Nerve-targeted options
Relevant when examination identifies a superficial neuropathic pattern or a compressed peripheral nerve—not simply because pain is present.
Lyftogt perineural therapy (perineural injection therapy) A series of small dilute dextrose injections just under the skin, over tender superficial nerves. Only if relevant
What it involves
Small injections of low-concentration dextrose, usually 5%, placed just beneath the skin along tender superficial nerves. Given as a series of short sessions.
What the evidence shows
The dextrose nerve evidence is in peripheral entrapment — carpal tunnel and cubital tunnel — not in nerve root compression from the spine.
Pairing reviewed 2026-08-30.
Where it fits for you
Not a treatment for a compressed nerve root. Considered only where a separate peripheral entrapment is also present.
Ultrasound-guided nerve hydrodissection Fluid placed around a nerve to free it from the surrounding tissue. Only if relevant
What it involves
Under ultrasound, fluid is placed in the plane around the nerve to separate it from the tissue that is tethering or compressing it.
What the evidence shows
The dextrose nerve evidence is in peripheral entrapment — carpal tunnel and cubital tunnel — not in nerve root compression from the spine.

Where it fits for you
Not a treatment for a compressed nerve root. Considered only where a separate peripheral entrapment is also present.
This is general information only and suitability is assessed individually. Treatments with limited or condition-dependent evidence may still be discussed, but only with clear explanation of the uncertainty, the expected benefit, risks, cost and alternatives. Red flags, progressive neurological symptoms or suspected serious pathology require a different pathway.
Every treatment above is described in full on the non-surgical treatments page, including what each one is used for and what the evidence supports. Ratings apply to the named diagnosis; an adjacent muscle, tendon, joint or nerve problem is assessed as a separate target.
Corticosteroid injection is reviewed separately for each diagnosis.
Cortisone reliably reduces pain in the short term, and that can be genuinely useful when pain is stopping you sleeping or moving enough to rehabilitate. Beyond that window the picture changes. A systematic review of 41 randomised trials and 2,672 participants found that corticosteroid injection reduced pain in the short term but that the effect reversed at intermediate and long term; in pooled analysis for lateral epicondylalgia the short-term effect was large (SMD 1.44, 95% CI 1.17 to 1.71) while no intervention was favoured at 26 weeks (-0.40, -0.67 to -0.14) and at 52 weeks (-0.31, -0.61 to -0.01) (Coombes, Lancet 2010). In a randomised trial in lateral epicondylalgia, 83 per cent of the corticosteroid group had completely recovered or much improved at one year against 96 per cent given a placebo injection, and recurrence ran at 54 per cent against 12 per cent; adding physiotherapy made no significant difference at one year (Coombes, JAMA 2013). In joints, repeated corticosteroid injections have been associated with cartilage loss. It does not repair anything.
So we do not build treatment plans around it. Where an injection is the right call, we review the specific diagnosis and target, discuss what is being injected and why, keep the number low, and pair it with the loading work that changes the longer-term course.
When we would still consider it
- Pain severe enough to block rehabilitation
- A clear inflammatory or bursal target on imaging
- A specific short-term goal — a trip, a procedure, a return to work
- Diagnostic use, where the response tells us where the pain is coming from
