What neuropathy feels like
Peripheral neuropathy most often starts in the feet as burning, tingling or numbness that may spread upward. Some people feel electric shocks or sharp pain at night; others notice weakness or imbalance. Diabetes, vitamin B12 deficiency, thyroid or kidney issues, certain medications and alcohol are common contributors, but thorough history often reveals multiple factors.
- Burning/tingling in feet or hands
- Numbness, reduced sensation, night worsening
- Weakness or imbalance in advanced cases

How evaluation is structured
History maps distribution, duration, metabolic and medication contributors; sensory and motor exam localizes the pattern; nerve conduction studies (NCS/EMG) and labs are discussed only when they would change management. Education covers glucose and nutrition optimization, foot care and fall prevention — no promised reversal in chronic disease is implied.
When nerve studies help
NCS/EMG helps distinguish axonal vs demyelinating patterns, localizes entrapment, and quantifies severity for follow-up. It is most informative when symptoms fit a length-dependent neuropathy or when focal weakness suggests compression.
| Question | Test consideration |
|---|---|
| Diffuse feet tingling + diabetes | NCS + B12, HbA1c, thyroid |
| Hand tingling at night | NCS for carpal tunnel |
| Rapid weakness | Urgent exam ± EMG |
