From the Guidelines
The initial evaluation for a patient with peripheral neuropathy and neck pain should include a comprehensive history, physical examination, and targeted diagnostic testing, with first-line diagnostic tests including complete blood count, comprehensive metabolic panel, HbA1c, vitamin B12, folate levels, thyroid function tests, and erythrocyte sedimentation rate, as recommended by recent guidelines 1. Begin by obtaining details about symptom onset, progression, distribution, quality of pain, aggravating/alleviating factors, and associated symptoms. Physical examination should assess sensory function (light touch, pinprick, vibration, proprioception), motor strength, deep tendon reflexes, and cervical spine range of motion. Consider cervical spine imaging (X-ray initially, MRI if radiculopathy is suspected) to evaluate for structural causes of neck pain that might contribute to neuropathic symptoms, as suggested by the American College of Radiology 1. Management typically begins with addressing underlying causes if identified. For symptom control, start with acetaminophen 650-1000mg every 6 hours or NSAIDs like ibuprofen 400-600mg three times daily for neck pain. For neuropathic pain, consider gabapentin (starting at 300mg daily, gradually increasing to 300mg three times daily) or pregabalin (starting at 75mg twice daily), as recommended by the Mayo Clinic Proceedings 1 and Diabetes Care 1. Physical therapy focusing on cervical spine stabilization exercises and proper ergonomics can help reduce mechanical neck pain. Patients should be counseled on activity modification and the importance of maintaining proper posture. This approach addresses both the potential mechanical factors from the neck that might contribute to neuropathy and the neuropathic symptoms themselves while investigations for underlying causes continue. Key points to consider in the management of neuropathic pain include:
- Identifying and treating underlying causes
- Using first-line medications such as gabapentin, pregabalin, or duloxetine
- Considering alternative therapies such as physical therapy or cognitive behavioral therapy
- Monitoring for potential side effects and adjusting treatment as needed
- Providing patient education on activity modification and proper posture to reduce mechanical neck pain.

From the Research
Initial Evaluation
The initial evaluation for a patient presenting with peripheral neuropathy and neck pain involves a comprehensive history, physical examination, and judicious laboratory testing 2, 3. The diagnosis requires careful clinical assessment to localize the lesion to the peripheral nerves, identify the underlying etiology, and exclude potentially treatable causes.
Laboratory Tests
Initial blood tests should include:
- Complete blood count
- Comprehensive metabolic profile
- Measurement of erythrocyte sedimentation rate
- Fasting blood glucose
- Vitamin B12
- Thyroid-stimulating hormone levels 2, 3, 4 Specialized tests, such as serum protein electrophoresis with immunofixation, may be ordered if clinically indicated 3, 4.
Additional Testing
Electrodiagnostic studies, including nerve conduction studies and electromyography, can help in the differentiation of axonal versus demyelinating or mixed neuropathy 2, 5. Lumbar puncture and cerebrospinal fluid analysis may be helpful in the diagnosis of Guillain-Barré syndrome and chronic inflammatory demyelinating neuropathy 2. Nerve biopsy may be considered if the diagnosis remains unclear 2.
Management
Treatment should address the underlying disease process, correct any nutritional deficiencies, and provide symptomatic treatment 2, 3. Several classes of medications, including gabapentinoids and antidepressants, can help alleviate neuropathic pain 3, 4.
Considerations for Neck Pain
While the provided evidence primarily focuses on peripheral neuropathy, it is essential to consider the potential relationship between neck pain and peripheral neuropathy. A comprehensive evaluation should include an assessment of the neck and consideration of potential causes of neck pain that may be contributing to or exacerbating the peripheral neuropathy. However, specific laboratory tests for neck pain are not outlined in the provided evidence.
