Treatment of Cervical Radiculopathy with Arm Pain, Numbness, and Tingling
For a patient presenting with radiculopathy symptoms including arm pain, numbness, and tingling with underlying neck pain, initiate conservative management without immediate imaging unless red flags are present, as 75-90% of cases resolve spontaneously within 6-8 weeks. 1, 2
Initial Clinical Assessment: Screen for Red Flags
Before proceeding with any treatment or imaging, systematically evaluate for the following urgent conditions that require immediate MRI cervical spine without contrast 3, 2:
- Constitutional symptoms: fever, unexplained weight loss, night sweats 3
- History of malignancy or risk factors for metastatic disease 3, 2
- Immunosuppression or history of IV drug use (infection risk) 3
- Progressive motor weakness or neurological deficits 3, 2
- Bilateral symptoms suggesting myelopathy 1
- Myelopathic signs: gait disturbance, bowel/bladder dysfunction, loss of perineal sensation 1, 4
- Intractable pain despite appropriate conservative therapy 3, 2
- Vertebral body tenderness on palpation 3, 2
- Elevated inflammatory markers: ESR, CRP, WBC count 3
Conservative Management Protocol (First-Line Treatment)
If no red flags are present, defer imaging and initiate the following conservative treatment regimen 1, 2, 5:
Pharmacologic Management
- First-line medications: Acetaminophen, NSAIDs, or COX-2 inhibitors 6
- Short-term muscle relaxants may be considered for acute symptoms 6
- Opioids: Use only if other treatments are ineffective, and continue only if improved function outweighs impairment 6
- Adjuvant medications: Consider antidepressants or anticonvulsants for neuropathic pain symptoms (numbness, tingling) 6
Physical Modalities
- Cervical collar: Short-term immobilization only (avoid prolonged use) 5
- Cervical traction: May temporarily decompress nerve impingement 5
- Physical therapy: Improves neck discomfort and function 5
- Multimodal approach: Combination of medications, physical therapy, and modalities provides optimal benefit 5
Reassessment Timeline
Re-evaluate at 4-6 weeks to determine if symptoms are resolving, stable, or progressing 1, 6:
- If improving: Continue conservative management
- If persistent beyond 6-8 weeks without improvement: Proceed to MRI cervical spine without contrast 1, 4, 2
- If new neurological symptoms develop: Obtain immediate MRI 1
Imaging Strategy When Indicated
MRI cervical spine without contrast is the preferred imaging modality when conservative management fails or red flags are present 3, 4, 2:
- MRI correctly predicts 88% of cervical radiculopathy lesions compared to 81% for CT myelography 3, 2
- MRI is superior to CT for identifying nerve root compression and soft tissue abnormalities 4, 2
- CT myelography: Reserve for patients with MRI contraindications or equivocal MRI findings with clinically apparent radiculopathy 3, 2
Critical Pitfalls to Avoid
- Do not order immediate imaging in acute presentations without red flags: Degenerative changes are present in 85% of asymptomatic individuals over 30 years and 65% of asymptomatic patients aged 50-59, correlating poorly with symptoms 3, 4, 2
- Do not skip red flag screening: Missing serious pathology (infection, malignancy, myelopathy) can lead to devastating outcomes 3, 2
- Do not interpret imaging findings without clinical correlation: High rates of false-positive and false-negative findings exist even on MRI 3, 2
- Do not use prolonged cervical collars: Short-term use only to avoid deconditioning 5
Surgical Referral Indications
Consider surgical evaluation for 7, 8:
- Severe or progressive neurological deficits despite conservative management 7
- Intractable pain after 6-8 weeks of adequate conservative treatment 7
- Confirmed nerve root compression on MRI with corresponding clinical symptoms that fail conservative therapy 7, 8
