Cervical Radiculopathy
A compressed nerve root in the neck causing arm pain, numbness, and tingling
ICD-10: M54.12 · cervical condition
A pinched nerve in the neck — medically known as cervical radiculopathy — occurs when a nerve root in the cervical spine becomes compressed or irritated. With an annual incidence of approximately 83 per 100,000 people, it is one of the most common cervical spine disorders. The condition most frequently affects the C6 and C7 nerve roots (accounting for roughly 70% of cases), typically due to disc herniation in younger patients (under 40) or foraminal stenosis from spondylosis in older adults. The result is often sharp or burning pain that radiates from the neck into the shoulder, arm, or hand in a dermatomal pattern, sometimes accompanied by numbness, tingling, or weakness. The natural history is generally favorable — approximately 80–90% of patients improve with conservative management alone.
83
The annual incidence of cervical radiculopathy is approximately 83 per 100,000 people, with peak occurrence between ages 50–54.
Radhakrishnan K et al., Brain (1994)75–90%
Approximately 75–90% of cervical radiculopathy cases improve within 4–6 weeks with conservative treatment including physical therapy and anti-inflammatory medications.
North American Spine Society93–97%
ACDF (anterior cervical discectomy and fusion) achieves excellent or good outcomes in 93–97% of appropriately selected patients at 2-year follow-up.

The cervical spine consists of seven vertebrae (C1–C7). Eight pairs of cervical nerve roots exit through the neural foramina — openings formed by the pedicles of adjacent vertebrae. Unlike the rest of the spine, cervical nerve roots are named for the vertebra below them (the C6 root exits above C6). The neural foramen is bounded by the uncovertebral joint anteriorly, the facet joint posteriorly, and the pedicles above and below. Any structure that encroaches on this space — a herniated disc, osteophyte, or thickened ligament — can compress the exiting nerve root. The C5–C6 and C6–C7 levels are most commonly affected because they bear the greatest mechanical load and have the most cervical motion.
Symptoms
- Sharp or burning pain in the neck that radiates into the shoulder, arm, or hand in a specific nerve pattern
- Numbness or tingling in the fingers or hand — C6 affects the thumb and index finger, C7 the middle finger, C8 the ring and little finger
- Weakness in the arm, forearm, or grip — may affect specific movements (e.g., C7 weakness impairs triceps and wrist extension)
- Pain that worsens with turning or tilting the head toward the affected side (Spurling maneuver)
- Symptoms that ease when raising the arm above the head (Shoulder Abduction Relief Sign)
- Neck stiffness or reduced range of motion
- Pain that may be mistaken for shoulder pathology — especially with C5 radiculopathy
Causes & Risk Factors
- Cervical disc herniation pressing on a nerve root — the most common cause in patients under 40
- Bone spurs (osteophytes) from cervical arthritis or degenerative disc disease — most common cause in patients over 50
- Cervical foraminal stenosis narrowing the opening where the nerve root exits
- Spondylosis — age-related wear-and-tear changes in the cervical spine affecting discs, facets, and uncovertebral joints
- Injury or trauma (such as whiplash) causing acute disc or joint damage
- Repetitive occupational strain from prolonged overhead work, heavy lifting, or poor ergonomics
Diagnosis
- Radicular arm pain following a dermatomal pattern corresponding to a specific nerve root (C5: lateral arm; C6: lateral forearm and thumb; C7: middle finger; C8: ring and small finger)
- Spurling test positive — neck extension and ipsilateral rotation reproduces or worsens arm symptoms
- Shoulder abduction relief sign — overhead arm positioning reduces symptoms
- MRI showing disc herniation or foraminal narrowing at the level matching the clinical pattern
- Diminished deep tendon reflexes at the affected level (C5: biceps; C6: brachioradialis; C7: triceps)
- EMG/NCS may show acute denervation in muscles innervated by the affected root (used when diagnosis is uncertain)
Treatment Options
Conservative
- Physical therapy targeting cervical stabilization, postural correction, and nerve gliding exercises
- Non-steroidal anti-inflammatory drugs (NSAIDs) to reduce pain and swelling
- Oral corticosteroids (short course, typically 5–7 days) for acute flares with severe pain
- Gabapentin or pregabalin for neuropathic pain symptoms (burning, tingling, electric-shock sensations)
- Cervical epidural steroid injections — transforaminal or interlaminar approach — to relieve nerve root inflammation
- Soft cervical collar (short-term use only, 1–2 weeks) for acute symptom relief
- Activity modification and ergonomic improvements at home and work — monitor position, desk setup
- Traction therapy — manual or mechanical — to open the foramen and reduce nerve compression
Surgical
- Anterior cervical discectomy and fusion (ACDF) — removes the disc and fuses adjacent vertebrae; the most commonly performed cervical spine surgery
- Cervical disc arthroplasty (total disc replacement) — alternative to fusion that preserves segmental motion; FDA-approved for single and some two-level disease
- Posterior cervical foraminotomy — removes bone or disc material to widen the nerve exit without fusion; best for lateral soft disc herniations
- Cervical laminoplasty — for multi-level compression causing myelopathy alongside radiculopathy
Treatment Comparison
When to see a spine specialist
See a spine specialist if arm pain, numbness, or weakness persists beyond 4–6 weeks of conservative care, if symptoms are rapidly worsening, or if you develop difficulty walking or coordination problems (which may indicate myelopathy). Progressive weakness in the hand or arm — such as difficulty gripping, buttoning shirts, or dropping objects — should prompt urgent evaluation.

Most patients with cervical radiculopathy begin to improve within 4–6 weeks of starting conservative treatment, with 80–90% achieving satisfactory outcomes by 3–6 months
If surgery is needed, ACDF patients typically return to desk work within 2–4 weeks and physically demanding work within 6–12 weeks
Long-term studies show surgical outcomes remain excellent at 5–10 year follow-up
Frequently Asked Questions
Can a pinched nerve in the neck heal on its own?
Yes — many cases of cervical radiculopathy resolve with conservative treatment over weeks to months. Studies show that 80–90% of patients improve without surgery within 4–6 months. The herniated disc material that compresses the nerve can shrink as the body reabsorbs it over time, relieving pressure naturally. A 2010 systematic review found that cervical disc herniations can decrease in size or resolve completely in a significant proportion of patients.
What does a pinched nerve in the neck feel like?
Most patients describe it as a sharp, burning, or electric-shock pain that starts in the neck or shoulder and travels down the arm into the hand or fingers. Some also notice numbness or tingling in a specific area of the arm or hand, and weakness when gripping or lifting. The exact pattern depends on which nerve root is affected — C6 radiculopathy typically causes thumb and index finger symptoms, while C7 affects the middle finger and triceps strength.
How is cervical radiculopathy diagnosed?
Diagnosis typically begins with a physical exam and medical history. Your doctor will test your reflexes, strength, and sensation in the arm and look for provocative signs like a positive Spurling test (neck extension toward the painful side reproduces arm symptoms). An MRI of the cervical spine is the most useful imaging study — it shows disc herniations, bone spurs, and nerve compression. EMG/nerve conduction studies may be ordered to confirm which nerve is affected, particularly if the MRI findings don't clearly correlate with symptoms.
Is cervical radiculopathy the same as a herniated disc?
Not exactly. Cervical radiculopathy is a clinical syndrome — nerve root irritation causing arm symptoms — that can be caused by a herniated disc, but also by bone spurs, arthritis, or foraminal stenosis. A herniated disc is one of the most common structural causes in younger patients, while spondylosis (degenerative arthritis) is the leading cause in patients over 50. The two terms describe different things: one is the symptom pattern (radiculopathy) and the other is a structural finding (herniated disc).
What happens if cervical radiculopathy is left untreated?
In many cases, the condition improves on its own. However, if a nerve root remains compressed for a prolonged period (generally months to years), there is a risk of permanent nerve damage, resulting in lasting weakness or numbness in the arm. If symptoms include difficulty walking, balance problems, or loss of hand coordination, seek prompt evaluation — this may indicate myelopathy (spinal cord compression), which is a separate and more serious condition that may require urgent surgery.
