Back Pain Doctor
Cervical Radiculopathy
Written by Dr Joshua Hatch, Musculoskeletal GP, RACGP Fellow, Diploma in Musculoskeletal Medicine (FSEM UK).
Cervical radiculopathy is a nerve-root pain pattern from the neck. The pain often travels beyond the neck into the shoulder blade, arm or hand. Some people notice tingling, numbness or weakness in a pattern that helps identify which nerve root may be involved.
Assessment focuses on neurological function, symptom behaviour and whether imaging is needed. The goal is to separate stable nerve irritation from more concerning patterns that need urgent review.
Non-surgical care may include education, activity modification, medication review, physiotherapy, gentle nerve mobility work and gradual strengthening. Treatment depends on the severity, neurological findings and how symptoms are progressing.
Common symptoms
- Neck pain with pain travelling into the shoulder, arm or hand
- Pins and needles, numbness or altered sensation
- Weakness in selected arm or hand movements
- Symptoms aggravated by neck position, coughing or prolonged sitting

Evidence for twelve treatment options in cervical radiculopathy
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
A Cochrane review of injection therapies for mechanical neck disorders, with or without radicular findings, found intramuscular lignocaine into myofascial trigger points better than placebo in the short term (SMD -1.36, 95% CI -1.93 to -0.80; NNT 3) and better than dry needling, while botulinum toxin was no better than saline across five trials (Peloso, Cochrane Database Syst Rev 2007). Active trigger points were present in 51% of 244 people with cervical radiculopathy and in none of 122 healthy controls, and halved after two weeks of conservative treatment (Sari, Eur J Phys Rehabil Med 2012). Held here rather than rated higher because the pooled effect rests on two small short-term trials of local anaesthetic, not the dilute glucose used in this clinic.
Pairing reviewed 2026-09-07.
Where it fits
Directed at levator scapulae, splenius capitis, the rhomboids or upper trapezius where examination finds a tender band reproducing part of your pain. It does not decompress a nerve root, and the arm symptoms are managed on their own terms.
Ultrasound-guided injections Guidance means the needle can be seen reaching the target. What goes into the needle depends on the diagnosis. Conflicting evidence
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 syntheses do not agree. The American Academy of Neurology review of 90 randomised trials pooled cervical with lumbar radiculopathy and found epidural corticosteroid probably reduces short-term pain (success rate difference -24.0%, 95% CI -34.9 to -12.6, about one extra person helped for every four treated) and short-term disability (-16.0%, -26.6 to -5), with insufficient evidence on long-term pain (Armon, Neurology 2025). A review of neck disorders describes the evidence for epidural corticosteroid in cervical radiculopathy as conflicting, and notes how few trials exist for any neck treatment at all (Cohen, Mayo Clin Proc 2015). These injections are placed under X-ray or CT. Ultrasound has been shown accurate at the cervical facet joints: 92% to 98% of 60 joints were confirmed intra-articular on contrast arthrography (Bodor, Spine J 2022). But a facet joint is not a nerve root, and that accuracy does not transfer.
Pairing reviewed 2026-09-17.
Where it fits
Not performed here. Where arm pain is severe or is not settling, this is a referral conversation about an X-ray or CT-guided cervical injection, weighed against the fact that most cervical radiculopathy settles with time and graded loading. New or progressive weakness, clumsiness of the hands or change in walking needs assessment rather than 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 overviewRadial shockwave (radial pressure wave) Broad treatment across tender muscle and fascia, close to the surface. Not for the nerve root
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. On 11 November 2026 shockwave, shock wave and ESWT crossed with cervical radiculopathy, cervical radicular pain and cervical disc herniation returned three records, none of them about the neck: they were case reports of low back and pelvic pain. A second search using radial and pressure-wave wording with radiculopathy, stenosis and sciatica in the neck or low back returned one record, a lumbar study (Rashad, Ann Rehabil Med 2025). Neither search found a trial of radial shockwave in people with a compressed nerve root in the neck.
Pairing reviewed 2026-11-11.
Where it fits
Not a treatment for a compressed nerve root. Considered only for a separate tender neck or shoulder muscle, once the arm symptoms are being managed on their own terms; new weakness needs assessment first.
Focused shockwave (ESWT) A true shock wave converging at depth: for tendon, joint, ligament and bone. Not for the nerve root
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 used 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
A tested absence: shockwave, shock wave, ESWT and pressure wave crossed with cervical radiculopathy returned no clinical record on 19 October 2026, and the wider search of radiculopathy and disc herniation (ten records) contained none in the neck. The neck-muscle trials of focused shockwave (Senlikci, Lasers Med Sci 2025; Vasvit, Complement Ther Med 2025) did not enrol people with nerve-root symptoms.
Pairing reviewed 2026-10-19.
Where it fits
Not a treatment for a compressed nerve root. Considered only for a separate tender neck or shoulder muscle, once the arm symptoms are being managed on their own terms; new weakness needs assessment first.
EMTT (magnetotransduction therapy) High-energy magnetic pulses applied over the area. Usually painless, no contact. Plausible: no studies
What it involves
You sit with the applicator positioned over the area for a short session. It is usually painless and needs no gel or skin contact. It is usually given 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 could be identified. 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
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 it is described 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. Worth discussing
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
One small study exists. Ninety patients with cervical radiculopathy were allocated across six treatments; the group given four periradicular platelet-rich plasma injections had the largest falls in pain (70.6%) and neck disability (56.6%) at two-month follow-up, with a 25% reduction in nerve root cross-sectional area (Godek, Ortop Traumatol Rehabil 2020). It was unblinded, had no placebo group, and had roughly fifteen people in each arm.
Pairing reviewed 2026-09-03.
Where it fits
Not done in this clinic. An injection at a cervical nerve root should be performed under CT guidance, so where it is warranted you are referred to a radiologist to perform it that way. Most nerve root symptoms in the neck settle over time with rehabilitation, so this is a conversation for pain that has not followed that course, and the single unblinded study behind it is part of that conversation.
Prolotherapy (dextrose) A course of dextrose injections into and around the structure and its attachments. Plausible: no studies
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
A PubMed search for prolotherapy or dextrose injection in cervical radiculopathy returns no trial. The published material is narrative reviews and single cases. A practitioner survey of spinal prolotherapy recorded 472 adverse events including 54 nerve injuries (Dagenais, Arch Phys Med Rehabil 2006), and one report describes cervical spinal cord injury following upper cervical prolotherapy (Yun, Ann Rehabil Med 2011).
Pairing reviewed 2026-09-05.
Where it fits
Not offered for arm pain coming from a nerve root. Reserved for a separately identified neck ligament or attachment problem once the radicular symptoms have settled.
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
Searching hyaluronic acid, hyaluronate and viscosupplementation against cervical radiculopathy, cervical disc, cervical epidural and brachialgia returns no records at all. The lumbar work does not carry across: the one randomised trial there added hyaluronic acid to a nerve root block rather than injecting a joint, and its only advantage was less pain in the first fortnight after the procedure (Ko, Spine J 2018).
Pairing reviewed 2026-09-20.
Where it fits
Not offered for this problem. A pinched nerve root in the neck is not treated by lubricating a 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
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 in cervical radiculopathy. The only record near it is a case series of subcutaneous dextrose over muscle attachments in which one person had shoulder weakness six years after a cervical radiculopathy, and the outcome measured was strength, not pain (Meyers, Cureus 2025). The cervical dextrose studies inject at the nerve root itself, which is the hydrodissection row on this page (Lin, Sci Rep 2023).
Pairing reviewed 2026-10-29.
Where it fits
Not a treatment for a compressed cervical nerve root. Considered only where a separate tender superficial nerve in the neck, shoulder or arm is also part of the picture.
Ultrasound-guided nerve hydrodissection Fluid placed around a nerve to free it from the surrounding tissue. Retrospective studies only
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. Two retrospective studies and two case reports, no randomised trial. In 74 consecutive people with arm pain from a cervical nerve root, ultrasound-guided hydrodissection of the root with 10 mL of 5% dextrose, 0.2% lignocaine and 4 mg betamethasone reduced pain at one week, one month, three months and final follow-up (3 to 20 months), equally in mild and in moderate-to-severe narrowing of the exit canal; four (5.4%) had brief dizziness (Lin, Sci Rep 2023). The mixture contained cortisone, so the result cannot be put down to the fluid alone. In a multicentre retrospective comparison of 199 people with cervical spondylotic radiculopathy, adding ultrasound-guided hydrodissection of the brachial plexus in the scalene space to acupotomy gave lower neck disability and pain scores at 4, 8 and 16 weeks than acupotomy alone, with no nerve injury or infection; patients were not randomised and the injectate is not stated (Shang, Front Aging Neurosci 2026). Two single cases describe dextrose around a cervical root (Wu, Cureus 2024; Pan, Pain Med Case Rep 2025). The nearest randomised evidence is indirect: in 40 people with cervical radiculopathy, a nerve-root injection of saline with local anaesthetic did as well as one with cortisone at three weeks (Anderberg, Eur Spine J 2006).
Pairing reviewed 2026-10-29.
Where it fits
Discussed alongside a neck and nerve-mobility rehabilitation program where arm pain from a cervical nerve root has not settled, as an alternative to a cortisone nerve-root injection or a step before a surgical opinion. Progressive weakness or any sign of spinal cord compression needs imaging and a surgical opinion first.
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.
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 neck 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.
