Diagnosis
Healthcare providers diagnose the cause of numbness through:
- Medical history: Detailed questioning about symptoms, onset, and triggers
- Physical examination: Testing sensation, reflexes, and muscle strength
- Neurological tests: Assessing nerve function and response
- Blood tests: Checking for diabetes, vitamin deficiencies, thyroid function
- Nerve conduction studies: Measuring electrical signals in nerves
- Electromyography (EMG): Testing muscle response to nerve signals
- Imaging tests: MRI, CT scan, or X-rays to identify structural issues
- Lumbar puncture: If central nervous system disorder suspected
Treatment Options
Conservative Treatments
- Rest and activity modification
- Physical therapy exercises
- Occupational therapy
- Ergonomic adjustments

- Massage therapy
- Acupuncture
- Stress reduction techniques
Medical Treatments
- Pain medications: For associated discomfort
- Anti-inflammatory drugs: To reduce nerve inflammation
- Antidepressants: For neuropathic pain
- Anti-seizure medications: For nerve pain
