Sciatica Treatment Brisbane | Back Pain Doctor

Written by Dr Joshua Hatch, Musculoskeletal GP, RACGP Fellow, Diploma in Musculoskeletal Medicine (FSEM UK).

Sciatica describes pain that radiates from the lower back or buttock down the leg, usually caused by irritation or compression of a nerve root in the lower spine. Most cases improve over time with appropriate management.

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.

Most episodes of sciatica improve with time and non-surgical care, including staying as active as symptoms allow, physiotherapy and pain management. Recovery is often gradual.

Assessment looks at the pattern of symptoms, checks for any features that need further investigation or referral, and leads to a management plan. Where appropriate, options for pain control while the nerve settles are discussed, along with 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

Commonly seen in

Gym, strength and CrossFit Masters athletes and staying active

Every treatment reviewed for this diagnosis

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

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 a very dilute local anaesthetic (0.02-0.08%) 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). No trial of needling or injection into muscle was found for sciatica caused by a disc.

Pairing reviewed 2026-09-07.

Where it fits

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 patients are told so.

Ultrasound-guided injections Guidance means the needle can be seen reaching 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

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 and not something provided here. 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

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 overview

Radial 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). A two-group study of 60 people with sciatica from scarring after laminectomy found radial shockwave added to physiotherapy reduced pain more than physiotherapy alone, but randomisation is not stated (Rashad, Ann Rehabil Med 2025; added 19 October 2026).

Pairing reviewed 2026-09-13.

Where it fits

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.

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

Searched 20 October 2026: platelet-rich plasma with sciatica, radiculopathy or radicular pain and an epidural, transforaminal, nerve-root or perineural route (26 records), and a pass restricted to randomised trials and systematic reviews that added disc herniation (13 records). Every trial is of an injection beside the affected nerve root, always against cortisone and never against a dummy injection or rehabilitation alone. The largest gave 124 people an ultrasound-guided injection of PRP or cortisone and found no difference in pain, disability or nerve testing at any point over twelve months, with no complications in either group (Xu, Neural Plast 2021). The smaller trials show cortisone ahead in the first weeks and PRP ahead later: at six and twelve weeks in a trial of 107 (Sonkar, J Clin Orthop Trauma 2026), and at six weeks and six months in a double-blind trial of 46 that found no difference at one year (Gupta, Asian Spine J 2024). The pooled analyses agree on that shape but not on its size. In five trials and 310 people the two were level for pain (Muthu, Exp Biol Med 2025); in seven studies and 416 people cortisone gave better function at four weeks and nothing separated them later (Wang, J Orthop Surg Res 2025); in three trials and 132 people cortisone was better at one month and PRP 1.5 points better on the 0 to 10 pain scale at six months (Ermawan, Spine Surg Relat Res 2025); and a review of 13 spinal trials found PRP ahead at three to six months in the four nerve-root trials (Zhang, Eur Spine J 2026). A systematic review graded the certainty of the whole body of work very low (Kubrova, Biomedicines 2022).

Pairing reviewed 2026-10-20.

Where it fits

Not offered here: PRP is not injected into a disc or beside a nerve root in this clinic. Where sciatica has not settled, an image-guided injection beside the nerve root is a referral conversation with a radiologist or pain medicine specialist, and on these trials PRP is an alternative to cortisone there rather than a clear improvement on it. Most sciatica eases over weeks to months, and the rehabilitation program is what carries people through that time.

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). A 2026 pragmatic randomised trial adds a positive result against an active treatment rather than a placebo. In 104 people with at least three months of low back pain with leg pain (referred or radiating) scoring at least 6 out of 10, up to five monthly dextrose prolotherapy treatments beat up to three epidural steroid injections at 6 months (pain 5.1 against 7.2 out of 10) and 12 months (5.2 against 6.9), with better Oswestry disability scores (34 against 42 at 12 months) and no adverse events. Nobody was blinded, there was no dummy-injection group, and the abstract does not say where the dextrose was injected (Wende, PM R 2026).

Pairing reviewed 2026-10-29.

Where it fits

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.

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

Searched 29 October 2026: radiculopathy, radicular pain, sciatica, nerve root, disc herniation or spinal stenosis with dextrose, 5% glucose, D5W, hydrodissection, hydrorelease, perineural injection or neural prolotherapy (53 records, all read), with a randomised-trial pass, a systematic-review pass and a pass on ultrasound-guided cervical root injection. No study has tested dextrose injected just under the skin for sciatica. The dextrose trial in back pain spreading to the leg used a different route, the epidural space: in 35 people with back pain radiating to the buttock or leg, a single caudal epidural of 10 mL of 5% dextrose gave more relief than saline at four hours (84% against 19% with at least half their pain gone) and at 48 hours, but not at two weeks (Maniquis-Smigel, Anesth Pain Med 2016), and an uncontrolled follow-up of repeated epidurals reported pain 52% lower at a year (Maniquis-Smigel, J Altern Complement Med 2018). Neither is the under-the-skin technique this row describes.

Pairing reviewed 2026-10-29.

Where it fits

Not a treatment for an irritated lumbar nerve root. Considered only where a separate tender superficial nerve, such as a cluneal nerve over the buttock, is also part of the picture.

Ultrasound-guided nerve hydrodissection Fluid placed around a nerve to free it from the surrounding tissue. One uncontrolled series

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

Searched 29 October 2026: radiculopathy, radicular pain, sciatica, nerve root, disc herniation or spinal stenosis with dextrose, 5% glucose, D5W, hydrodissection, hydrorelease, perineural injection or neural prolotherapy (53 records, all read), with a randomised-trial pass, a systematic-review pass and a pass on ultrasound-guided cervical root injection. One uncontrolled series of the procedure at the lumbar nerve root: in 46 people with lumbar radiculopathy, ultrasound-guided hydrodissection of the nerve root with 10 mL of saline, contrast and 1% lignocaine (no cortisone) lowered leg pain from 7.1 to 5.0 out of 10 at one week, 4.2 at one month and 3.8 at three months, with 58% responding at three months and Oswestry disability falling from 42 to 28. There was no comparison group, the fluid stayed around the target root in only 30% of cases, and two people had brief radiating pain during the injection (Arima, Spine Surg Relat Res 2026). Hydrodissection of the sciatic nerve in the buttock is reported only in single cases and a four-person emergency department series (Silver, Am J Emerg Med 2023; Stenberg, J Emerg Med 2025). The randomised trials nearby tested cortisone with saline as the control, and they are a caution against reading too much into an uncontrolled result: in 160 people with sciatica, saline beside the nerve root gave less relief than cortisone at two weeks but less back pain at three and six months (Karppinen, Spine 2001), and in 116 people a caudal epidural of saline did no better than a sham injection under the skin at any point to a year (Iversen, BMJ 2011).

Pairing reviewed 2026-10-29.

Where it fits

Discussed for leg pain from a lumbar nerve root that has not settled with a rehabilitation program and time, as an alternative to a cortisone nerve-root injection, on the understanding that the evidence is one series without a comparison group. Progressive weakness, numbness in the saddle area or any bladder or bowel change needs urgent assessment, not an injection.

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. The method behind the ratings, and the treatments not offered, are set out on the evidence page.

A note on cortisone

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 treatment plans are not built around it. Where an injection is the right call, the specific diagnosis and target are reviewed, what is being injected and why is discussed, the number is kept low, and it is paired with the loading work that changes the longer-term course.

When it might still be considered

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 shows where the pain is coming from

When a cortisone injection is worth doing, and when it is not

Other back conditions

Pain in the same area can come from more than one source, and the label matters less than what the examination and history point to. These are the other guides for this region.

Frequently asked questions

How long does sciatica take to settle?

Many people improve over several weeks, though it can take longer. A gradual reduction in leg symptoms is a reassuring sign. Persistent or worsening symptoms should be reviewed.

When is sciatica an emergency?

Progressive leg weakness, numbness around the groin or buttocks, or problems controlling the bladder or bowel are red flags that need urgent assessment.

Do I need a scan or surgery?

Most sciatica settles without surgery, and imaging is not always required early on. Whether investigation is needed is assessed, and a surgical opinion is arranged only when it is indicated.
