physiotherapy for trapped nerves in the neck and shoulders

A trapped nerve in the neck or shoulder — medically called cervical radiculopathy — is compression or irritation of one of the nerve roots as it exits the cervical spine, most commonly the C6 or C7 root, producing radiating pain, pins and needles, numbness or weakness down the arm. It affects roughly 83 per 100,000 adults in the UK each year, peaks between ages 51 and 60, and — crucially — 75–90% of cases resolve fully within 4 to 12 weeks with structured conservative physiotherapy. This guide explains what a trapped nerve actually is, how a chartered physiotherapist diagnoses it, which exercises and treatments have the strongest evidence, the red-flag symptoms that need urgent referral, and how CK Physio treats trapped nerves across Hanwell, Ealing and West London.

What is a trapped nerve in the neck or shoulder?
A “trapped nerve” in the neck or shoulder almost always refers to cervical radiculopathy — compression, tension or chemical irritation of one of the eight cervical nerve roots as it exits the spine through the narrow opening called the neural foramen. The affected nerve root sends signals down a specific corridor in your arm (called a dermatome and myotome), which is why pain, pins-and-needles or weakness follow a recognisable pattern rather than the whole arm.
The common causes, in order of frequency by age group:
- Younger adults (30s–40s): Acute disc herniation — the gel-like centre of a cervical disc bulges or extrudes into the spinal canal and pushes against a nerve root. C6–C7 is the disc most likely to herniate (45–60% of all cervical herniations).
- Middle age (50s–60s): Disc degeneration — the disc loses height and hydration, narrowing the nerve-root exit. This is the biggest single cause of trapped nerves in this age group.
- Older adults (60+): Foraminal stenosis — bony overgrowth (osteophytes) at the facet joints narrows the nerve-root exit space. Typically slower-onset, progressive symptoms.
Less commonly, a “trapped nerve” in the shoulder region can reflect peripheral nerve entrapments (suprascapular, axillary, radial or median nerve), thoracic outlet syndrome, or brachial plexopathy — which is why accurate clinical diagnosis matters. The treatment path is different for each.
What does a trapped nerve feel like? Symptoms and patterns
The defining symptom of a trapped nerve in the neck is pain that radiates from the neck or shoulder into a specific part of the arm, usually accompanied by pins and needles, numbness or weakness in the same distribution. Neck pain may be mild or absent — the arm symptoms dominate.
Spurling's test — one of four clinical tests that together give 90% diagnostic certainty for a trapped cervical nerve.
Each nerve root has a predictable referral pattern. The most common are:
- C5 (about 5% of cases): Pain into the side of the upper arm; weakness lifting the arm out to the side (deltoid); reduced biceps reflex.
- C6 (around 20%): Pain and pins-and-needles down the outside of the arm into the thumb and index finger; weakness flexing the elbow; reduced biceps or brachioradialis reflex.
- C7 (>50% — the most common): Pain down the back of the arm into the middle finger; weakness straightening the elbow or extending the wrist; reduced triceps reflex.
- C8 (around 10%): Pain and numbness into the ring and little finger; weakness gripping and spreading the fingers.
- T1 (rare): Pain in the armpit and inside of the upper arm.
Classic features that help distinguish a trapped cervical nerve from other shoulder or arm problems:
- Symptoms often worse when turning the head toward the painful side or looking up
- Relief when the arm is raised overhead and resting on the head (the “shoulder abduction relief sign”)
- Pain that wakes you at night or is worse first thing in the morning
- Pins-and-needles in the hand that comes and goes with posture
- Hand weakness — dropping things, difficulty opening jars, weaker grip on one side
How is a trapped nerve diagnosed? The clinical examination
The gold-standard clinical diagnosis is the four-test cluster described by Wainner: Spurling's test, the Upper Limb Tension Test, cervical distraction test, and ipsilateral cervical rotation below 60 degrees. When all four are positive, the likelihood of a genuine cervical radiculopathy is approximately 90%. Your chartered physiotherapist will run these tests plus a full neurological assessment.
A typical 60-minute assessment at CK Physio includes:
- History: When it started, what makes it worse, what eases it, sleep quality, previous episodes, work and activity history, red-flag screening.
- Observation and cervical range of motion: How far you can rotate, flex, extend and side-bend — both actively (you do it) and passively (we assist).
- Neurological screen: Muscle power testing in each myotome (C5–T1), sensation testing in each dermatome, and deep tendon reflexes (biceps, brachioradialis, triceps).
- Special tests (the Wainner cluster): Spurling's (92% specific), Upper Limb Tension Test (86% specific), cervical distraction, and restricted rotation <60°.
- Differential diagnosis screen: Shoulder, thoracic outlet, peripheral nerve entrapments, brachial plexus, and any central cord signs.
- Red-flag check: Myelopathy signs, bilateral symptoms, gait change, bladder/bowel change, constitutional symptoms.
Most trapped nerves don't need imaging to diagnose. MRI is reserved for cases with significant motor weakness, red-flag symptoms, bilateral signs, or symptoms not improving after 6–8 weeks of quality conservative treatment. The reason: up to a third of asymptomatic adults over 40 have cervical disc changes on MRI, so imaging without a clinical picture to match it often leads to false alarms and unnecessary interventions.
What are the red flags? When a trapped nerve needs urgent care
Most trapped nerves are benign and resolve with conservative care — but a small number of symptom combinations indicate serious spinal pathology and need urgent medical assessment the same day or within 48 hours.
Red flags — seek urgent medical assessment if any of these appear:
- Bilateral arm symptoms — pain, numbness or weakness affecting both arms — suggests central cord compression rather than a single nerve root
- Leg weakness, poor balance or unsteady walking (myelopathy) — the cord itself may be compressed
- Bladder or bowel dysfunction — new urinary urgency, retention, incontinence
- Progressive motor weakness — arm getting noticeably weaker over days
- Hoffman's sign (reflex seen on exam), hyperreflexia, spasticity
- Severe unremitting night pain, fever, unexplained weight loss — possible infection or malignancy
- Recent significant trauma (fall, road-traffic accident)
- History of cancer with new back or neck pain
What to do: Contact your GP the same day, or go to A&E if symptoms are severe or rapidly progressing. Cervical myelopathy can cause irreversible neurological damage if not treated promptly.
Is it actually a trapped nerve? The differential diagnoses not to miss
Shoulder and arm pain can come from several different sources — and a trapped cervical nerve is just one of them. Distinguishing them correctly is what separates a helpful physiotherapy assessment from a frustrating one. These are the conditions that most commonly masquerade as a “trapped nerve”:
| Condition | Giveaway symptoms | Treatment differs |
|---|---|---|
| Cervical radiculopathy (true trapped nerve) | Dermatomal pain/numbness + reflex change + positive cluster tests; worse with neck position | Neural mobilisation + cervical manual therapy |
| Rotator cuff tear or tendinopathy | Pain at the shoulder tip, worse with arm movement, not neck movement; normal reflexes | Rotator cuff strengthening, shockwave |
| Thoracic outlet syndrome | Pain in multi-root distribution; worse with arm overhead; possibly pulse changes | Postural & scalene muscle work |
| Carpal tunnel syndrome | Numbness in thumb/index/middle finger; Tinel's and Phalen's tests positive at wrist | Wrist splint, nerve glides, ergonomics |
| Parsonage-Turner syndrome | Sudden severe shoulder pain followed by rapid weakness; pain then fades but weakness persists | Conservative, specialist review |
| Suprascapular nerve entrapment | Deep shoulder-blade pain; weakness in external rotation; normal neck | Targeted shoulder rehab; sometimes injection |
What's the best treatment for a trapped nerve? The evidence hierarchy
The strongest evidence supports conservative physiotherapy combining neural mobilisation, cervical manual therapy, exercise (particularly deep neck flexor training), and occasionally cervical traction for most patients with trapped nerves. Surgery is rarely required. Injections have a role in selected refractory cases. Here's how the main interventions compare, drawing on Cochrane reviews and NICE guidance:
Neural mobilisation and nerve gliding
The most evidence-supported intervention specifically for cervical radiculopathy. A 2022 comparative trial showed neural mobilisation plus cervical isometric exercise produced statistically superior pain and disability outcomes versus cervical exercise alone. Neural mobilisation works by restoring normal “gliding” of the nerve through its surrounding soft tissue when compression has caused adhesions and neural tension.
Cervical manual therapy and mobilisation
Royal Dutch Physiotherapy guidelines (2018) and other international guidance recommend cervical and thoracic mobilisation combined with exercise as first-line care for neck pain with radicular symptoms. Manual therapy provides short-term relief and makes the patient able to engage with active rehab.
Exercise therapy
A 2021 meta-analysis of 10 trials (871 participants) showed pooled pain reduction of −0.89 SMD (95% CI −1.34 to −0.44) on visual analogue scale and Neck Disability Index improvement of −3.60 (95% CI −6.27 to −0.94) — both statistically and clinically meaningful. Importantly, exercise benefits persist at follow-up, where manual therapy effects tend to fade.
Cervical traction (in combination only)
A 2022 systematic review found cervical segmental traction combined with nerve mobilisation outperforms continuous traction or waitlist control (pain MD −3.29; disability MD −15.9). Traction as a standalone therapy has weak evidence; combined with nerve glides and exercise, it has a useful role — particularly for acute severe pain.
Medication (NICE NG193)
Short courses of NSAIDs for pain relief are reasonable while conservative treatment takes effect. For neuropathic pain specifically, NICE NG193 recommends amitriptyline, duloxetine, gabapentin or pregabalin — started by a GP and monitored. Opioid use is discouraged for persistent musculoskeletal neuropathic pain.
Cervical epidural or nerve root block
Image-guided steroid injection can help persistent severe radicular pain that has not responded to 6–8 weeks of conservative care. Useful as a bridge to rehabilitation rather than a solution. There are rare but serious risks (cord injury, vascular events) which should be discussed by the injecting physician.
Surgery (ACDF or artificial disc)
Anterior cervical discectomy and fusion (ACDF) or cervical disc replacement is reserved for cases with progressive neurological deficit, significant motor weakness, severe pain failing 12+ weeks of conservative care, or red-flag pathology (myelopathy, tumour, fracture). Return-to-work rates at 3 years are approximately 72%; outcomes are best for single-level disease with clear imaging correlation.
Best exercises for a trapped nerve in the neck or shoulder
Neural mobilisation (nerve gliding) is the single most evidence-supported exercise for cervical radiculopathy.
A structured trapped-nerve programme layers five exercise types in sequence: pain-relieving positions, neural mobilisation, deep neck flexor activation, scapular and thoracic strengthening, and progressive loading. Each serves a specific purpose — skipping any one of them slows recovery.
1. Pain-relief positioning (from day one)
What: Lying flat with head supported on a single pillow, arms resting on pillows. The “shoulder abduction relief” position — arm raised overhead, hand resting on the head — often dramatically reduces pain for 10–20 minutes.
Why: Reduces nerve-root tension and allows sleep. Sleep quality predicts recovery speed.
2. Median/ulnar/radial nerve glides (week 1+)
What: Sliders — arm extended to the side, tilt the head away while bending the wrist down, then head back toward the arm as the wrist comes up. 10 slow repetitions, 3× daily. Your physiotherapist will pick the glide that matches your specific nerve root.
Why: Restores normal nerve mobility. The nerve is glued down by inflammation or compression; glides get it moving again without loading it.
3. Chin tuck / deep neck flexor activation (week 1+)
What: Supine or seated. Gently draw the chin straight back without tilting the head — creates a subtle “double chin.” Hold 10 seconds, 10 reps, 3× daily.
Why: Activates the deep neck flexors (longus colli / longus capitis) that stabilise the cervical spine. Weak deep flexors are almost universal in chronic neck pain.
4. Scapular retraction and thoracic mobility (week 2+)
What: Prone Y-T-I (or wall-based variants), scapular squeezes, thoracic extension over a foam roller. The upper-back muscles directly affect cervical posture.
Why: A stiff upper back forces the neck to do extra work. Restoring thoracic mobility reduces the load on the cervical nerve roots.
5. Progressive loading (week 3+)
What: Isometric neck strengthening (resistance against own hand), progressing to resistance-band cervical exercises. 10 reps, 3 sets, every other day.
Why: Builds the capacity needed to prevent recurrence. The tendinopathy literature (which applies here) shows that under-loading the late stages predicts relapse.
One caveat: some cervical movements may worsen symptoms in the first 1–2 weeks. Don't push into sharp nerve-root pain or increasing numbness. A chartered physiotherapist will programme this so each exercise progresses safely. If you're working from online videos without supervision, stop anything that increases pins-and-needles or weakness.
How long does a trapped nerve take to heal?
Most trapped nerves settle significantly within 4–6 weeks and are fully resolved by 12 weeks with appropriate physiotherapy. Meta-analysis data show 75–90% resolve in 4–12 weeks with conservative care; even untreated, ~85% resolve in 8–12 weeks spontaneously. At 3 years, 83% remain functionally well. Here's the typical trajectory at CK Physio:
Weeks 1-2
Settle pain & sleep
Positions of comfort, gentle neural glides, early chin-tuck. Pain relief is the goal. Short course of NSAIDs if appropriate. Expect 20–40% improvement.
Weeks 3-4
Restore mobility
Cervical & thoracic mobilisation, progressed nerve glides, scapular work. Most patients are 50–70% better by the end of week 4.
Weeks 5-8
Load & strengthen
Progressive cervical isometrics, thoracic strengthening, occupation-specific tasks. Most patients are 80–90% better and back to full work.
Weeks 9-12+
Prevent recurrence
Discharge with maintenance programme; ergonomic changes embedded. If <70% better, imaging and specialist review; 1 in 10 cases need additional intervention.
A typical CK Physio programme is 6–10 sessions over 8–12 weeks. If progress stalls by week 6, we reassess: is the diagnosis correct, is there a peripheral nerve problem on top of the cervical one, is there a red flag we missed, do we need imaging? Don't keep grinding through a programme that isn't working — re-investigate.
Desk work and trapped nerves: the Marcus ergonomic checklist
Ergonomic set-up fixes the load. Exercise fixes the capacity. You need both.
For office workers — our typical Marcus persona — the single biggest lever is the screen-to-eye-line relationship. A monitor below eye line means your head tilts down all day, multiplying the load on the cervical spine. At 15° of flexion, the head weighs the equivalent of 12 kg on the neck; at 45° it's 22 kg. A £40 laptop riser often resolves more chronic neck pain than any single physiotherapy exercise.
Checklist:
- Monitor top at eye height, screen an arm's length away. Use a riser or stack of books.
- External keyboard and mouse if working on a laptop — so the screen and keyboard can be at different heights.
- Chair with lumbar support; feet flat; knees roughly level with hips.
- Phone not held with the shoulder — use a headset or speaker.
- Reading posture: tablet or documents at similar height to the screen, not in the lap.
- Micro-breaks every 30–45 minutes — stand, look at the ceiling, rotate the neck, chin-tuck 5 times.
- Sleep: single medium-height pillow; avoid front-sleeping which forces neck rotation for hours.
- Driving: headrest touching the back of the head; seat upright; rear-view mirror adjusted so you have to sit tall to see it.

Frequently asked questions
How long does a trapped nerve in the neck last?
Most trapped nerves in the neck resolve within 4–12 weeks with conservative physiotherapy — 75–90% of cases. At three years, 83% of patients who had conservative care remain functionally well. A small minority (around 10%) go on to need additional intervention such as cervical epidural injection or surgery. The biggest predictor of recovery speed is early engagement with a structured exercise programme rather than passive rest or medication alone.
Should I rest or exercise a trapped nerve?
Exercise — but the right exercise. Bed rest is no longer recommended for cervical radiculopathy because it prolongs recovery and weakens the supporting musculature. Instead, stay active within pain tolerance, adopt positions that reduce nerve tension (including the shoulder abduction relief position during flares), and start a structured neural mobilisation and deep neck flexor programme within the first week. A chartered physiotherapist will tell you which exercises to start with based on the level involved and your irritability.
Can physiotherapy fix a trapped nerve?
Yes for the vast majority — 75–90% of cervical radiculopathies resolve fully with conservative physiotherapy. The most evidence-supported approach combines neural mobilisation, cervical and thoracic manual therapy, deep neck flexor training and scapular strengthening. Where physiotherapy does not fully resolve symptoms, it still reliably improves function and sets the ground for surgical recovery if that path becomes necessary.
Do I need an MRI for a trapped nerve?
Usually no, and often not in the first 6 weeks. MRI is indicated when there is significant motor weakness (MRC grade 3 or less), red-flag features (bilateral symptoms, myelopathy signs, bladder/bowel change), symptoms not improving after 6–8 weeks of quality conservative care, or a specialist is considering injection or surgery. Early MRI in uncomplicated cases often shows degenerative changes that are also present in pain-free people — leading to interventions that don't help.
Is a trapped nerve the same as cervical radiculopathy?
Broadly yes — “trapped nerve” is the everyday term; “cervical radiculopathy” is the medical term. Both describe compression or irritation of a cervical nerve root. Some people use “trapped nerve” more loosely to refer to any nerve symptom in the neck, shoulder or arm — which may include peripheral nerve entrapments (e.g. carpal tunnel) or thoracic outlet syndrome. A proper physiotherapy assessment clarifies which condition you actually have, because the treatment is different.
What's the best sleeping position for a trapped nerve in the neck?
Back sleeping with a single medium-height pillow that keeps the head in line with the spine — not so high the chin tucks toward the chest, not so low the head tips back. Side sleeping is a reasonable second best, again with a pillow that fills the gap between the shoulder and the ear to keep the neck neutral. Front sleeping (prone) forces prolonged neck rotation and consistently makes cervical radiculopathy worse. Some patients sleep better with a rolled towel under the neck or a supportive cervical pillow during flares.
Will a trapped nerve come back?
It can if the underlying driver isn't addressed. Strengthening the deep neck flexors, restoring thoracic mobility, and fixing the ergonomic or postural triggers that caused the first episode reduce recurrence substantially. At CK Physio we discharge every trapped-nerve patient with a maintenance programme — typically 3×/week for life, 15 minutes per session — because maintenance is cheap insurance against a second episode.
