Cervical Radiculopathy: When a Pinched Nerve in Your Neck Causes Arm Pain

What Is Cervical Radiculopathy?

Cervical radiculopathy is a pinched nerve in your neck that causes pain, numbness, tingling, or weakness radiating into your shoulder, arm, or hand. The compression happens where the nerve exits the spine.

It's the neck equivalent of sciatica (which affects leg nerves from the lower back).

What Causes It?

Disc Herniation

The most common cause in younger people (under 50). The disc's inner gel pushes out and compresses the nerve root.

Degenerative Changes

More common over 50:

  • Bone spurs (osteophytes)
  • Disc space narrowing
  • Facet joint arthritis
  • Foraminal stenosis (narrowing of nerve exit tunnel)

    • Other Causes

  • Trauma
  • Tumors (rare)
  • Infection (rare)

    • Symptoms by Nerve Root

    Each nerve root affects different areas:

    C5 (C4-C5 level)

  • Shoulder pain
  • Deltoid weakness (can't raise arm to side)
  • Numbness over outer shoulder
  • Biceps reflex may be diminished

    • C6 (C5-C6 level)

  • Pain to thumb and index finger
  • Bicep weakness
  • Numbness in thumb and index finger
  • Brachioradialis reflex affected

    • C7 (C6-C7 level)

  • Pain to middle finger
  • Triceps weakness (can't straighten elbow against resistance)
  • Numbness in middle finger
  • Triceps reflex affected

    • C8 (C7-T1 level)

  • Pain to pinky and ring finger
  • Hand grip weakness
  • Numbness in pinky and ring finger

    • Red Flags (Seek Immediate Care)

  • Progressive weakness
  • Difficulty walking or balance problems
  • Bladder or bowel changes
  • Weakness in both arms or legs
  • Severe, unrelenting pain

    • These could indicate spinal cord compression (myelopathy), which is a medical emergency.

    Diagnosis

    Physical Exam

    Spurling's test:

    Turn head toward painful side, extend neck, apply downward pressure. Reproduces arm symptoms if positive.

    Shoulder abduction test:

    Raising hand to rest on head relieves symptoms (takes tension off nerve).

    Imaging

    X-ray:

  • Shows bone alignment, disc space narrowing
  • Doesn't show soft tissue well

    • MRI:

  • Gold standard
  • Shows disc herniation, nerve compression
  • Rules out other pathology

    • EMG/NCS:

  • Confirms nerve involvement
  • Determines severity
  • Done if diagnosis unclear or surgery considered

    • Conservative Treatment

    The Good News

    Most cervical radiculopathy improves without surgery. Studies show:

  • 75-90% improve with conservative care
  • Improvement typically within 4-6 weeks
  • Complete resolution in 2-3 months for most

    • Initial Management

    Activity modification:

  • Avoid positions that worsen symptoms
  • Avoid heavy lifting
  • Ergonomic adjustments

    • Pain management:

  • NSAIDs (ibuprofen, naproxen)
  • Acetaminophen
  • Short course of oral steroids (sometimes)
  • Ice or heat (whichever helps)

    • Cervical collar:

  • Short-term use only (few days to 2 weeks)
  • Provides rest
  • Prolonged use weakens muscles

    • Physical Therapy

    Cervical traction:

  • Manual or mechanical
  • Opens up nerve space
  • Often very helpful

    • McKenzie exercises:

  • Chin tucks
  • Cervical retraction
  • Extension if tolerated

    • Nerve glides:

  • Gentle tensioning and releasing of the nerve
  • Improves nerve mobility

    • Strengthening:

  • Deep neck flexors
  • Scapular stabilizers
  • Postural muscles

    • Injections

    Epidural steroid injection:

  • Anti-inflammatory medication at nerve root
  • Can provide significant relief
  • Diagnostic and therapeutic
  • May be repeated 2-3 times

    • Exercises

    Chin Tucks

  • Sit or stand tall
  • Draw chin straight back (make double chin)
  • Hold 5 seconds
  • Repeat 10 times
  • Several times daily

    • Cervical Retraction with Extension

  • Start with chin tuck
  • Then gently look up
  • Only if it doesn't increase arm symptoms
  • 10 reps

    • Nerve Glides (Median Nerve Example)

  • Arm at side
  • Extend wrist and fingers
  • Abduct arm while tilting head away
  • Move gently in and out of tension
  • 10 reps, 3x daily

    • Scapular Squeezes

  • Squeeze shoulder blades together
  • Hold 5 seconds
  • 15 reps

    • Deep Neck Flexor Activation

  • Lie on back
  • Gently nod chin (like saying "yes")
  • Feel muscles at front of neck engage
  • Hold 10 seconds
  • 10 reps

    • When to Consider Surgery

    Indications

  • 6-12 weeks of failed conservative treatment
  • Progressive neurological deficit
  • Significant weakness
  • Intolerable pain affecting quality of life
  • Myelopathy (spinal cord compression)

    • Surgical Options

    ACDF (anterior cervical discectomy and fusion):

  • Most common
  • Removes disc, fuses vertebrae
  • Excellent outcomes

    • Posterior foraminotomy:

  • Opens up nerve tunnel from back
  • Preserves motion
  • Good for certain cases

    • Disc replacement:

  • Removes disc, replaces with artificial
  • Preserves motion
  • Specific indications

    • Recovery

  • Most go home same day or next
  • Collar for 2-6 weeks
  • Physical therapy 6-12 weeks
  • Full recovery 3-6 months

    • Prognosis

    Natural History

  • Most improve significantly within 6 weeks
  • 85-90% have good outcomes with conservative care
  • Surgery highly effective for appropriate cases

    • Recurrence

  • Possible at same or different level
  • Maintaining strength and posture helps prevent
  • Address risk factors

    • A pinched nerve in the neck is painful and scary, but most cases resolve without surgery. Give conservative treatment a solid 6-8 weeks before considering intervention. Chin tucks, traction, nerve glides, and time work for the majority. If you have progressive weakness or severe symptoms not responding to treatment, surgery is effective.
