Symptoms of Cervical Radiculopathy
Cervical radiculopathy presents as neck pain combined with unilateral arm pain, accompanied by varying degrees of sensory loss, motor weakness, and/or paresthesias in a specific nerve root distribution 1.
Core Clinical Presentation
The hallmark symptom pattern includes:
- Neck pain radiating into one arm - this is the most common presentation
- Sensory deficits - numbness, tingling, or altered sensation following a dermatomal distribution
- Motor weakness - affecting specific muscle groups corresponding to the compressed nerve root
- Pain distribution - may involve the scapula (72% of cases), with scapular pain potentially preceding arm pain by several weeks 2
Specific Nerve Root Patterns
The most commonly affected nerve roots and their presentations are:
- C7 radiculopathy (most common) - weakness in wrist extension, elbow extension; sensory changes in middle finger
- C6 radiculopathy (second most common) - weakness in elbow flexion, wrist extension; sensory changes in thumb and index finger
- C8 radiculopathy (third most common) - weakness in hand intrinsic muscles; sensory changes in ring and small fingers 3
Important Clinical Nuances
The physical examination findings correlate poorly with MRI evidence of nerve root compression 1. This creates a diagnostic challenge because:
- MRI shows high rates of both false-positive findings (abnormalities in asymptomatic patients >30 years old) and false-negative findings
- Spondylotic changes are commonly identified in patients >30 years regardless of symptoms 1
- Physical examination tests have limited positive predictive value for confirming cervical radiculopathy 1
Natural History
Most cases (approximately 90%) resolve spontaneously or with conservative treatment within 3-4 months 4. However, nearly 50% of patients may experience residual or recurrent pain up to 1 year after initial presentation 1.
Red Flag Symptoms Requiring Urgent Evaluation
Watch for these concerning features that suggest serious pathology:
- Trauma history
- Malignancy symptoms (weight loss, night pain)
- Fever or signs of infection
- History of IV drug use
- Progressive neurological deficits or myelopathy signs (gait disturbance, bowel/bladder dysfunction, hyperreflexia)
- Intractable pain despite therapy
- Vertebral body tenderness on palpation
- Elevated inflammatory markers (ESR, CRP, WBC) 1, 5
Common Diagnostic Pitfalls
Do not assume imaging abnormalities correlate with symptoms - degenerative findings are ubiquitous in patients over 30 and may be incidental 1. The diagnosis requires clinical correlation between symptoms, examination findings, and imaging. Electrodiagnostic studies can help confirm the diagnosis when symptoms are atypical or imaging is nonspecific 3.
Scapular pain is frequently overlooked but occurs in 72% of cervical radiculopathy cases and may be the presenting symptom before arm pain develops 2.
