Observe & prepare safely
Map the exact distribution of burning/numbness and note whether heat, standing, meals, GI symptoms, dry eyes/mouth or skin changes preceded or accompany the neuropathy.

Neuropathy symptoms with normal EMG or MRI: what could the tests have missed?
A normal EMG or MRI can be reassuring without answering every neuropathy question. The next step is to map the symptom distribution and chronology, understand what the previous tests can actually detect, and decide whether a smaller-fiber, metabolic, systemic or other branch remains worth evaluating.
This page is general research orientation. It cannot diagnose you or determine that it is safe to delay medical care.
Initial research compass
Three ways to make the next step more informative.
Audit records & evidence
Verify what the prior EMG/NCS and MRI can and cannot exclude, and review older B12, glucose, thyroid, protein studies and other relevant trends rather than only the latest result.
Bring a focused question to a clinician
Ask neurology whether the phenotype could involve small fibers or another process not captured by routine EMG, and which targeted exam or test would best discriminate that branch.
Important: these are research-orientation ideas, not instructions to self-diagnose, stop prescribed treatment, or perform unsafe home testing. If symptoms may be urgent, seek appropriate in-person care first.
Why a deeper interview can help
A short web page cannot reconstruct a longitudinal medical case.
A full WhatDx case can ask follow-up questions based on your answers, review the records you upload, reconstruct chronology, track treatment response and compare competing explanations across specialties. It then produces a research dossier that you can discuss with a clinician.
The free suitability check is the right next step if you want a case-specific answer about whether that process is likely to add value.

Before you use this guide.
Is this page telling me what condition I have?
No. The same symptom pattern can have many causes, and this page does not have your full history, examination or records. It is intended to organize useful questions, not name a diagnosis.
What if my previous tests were “normal”?
Normal results can be genuinely reassuring, but their meaning depends on what was tested, when it was tested and which question the test can actually answer. A research process can help map that context without assuming that “normal” means “nothing is wrong.”
What does the paid WhatDx session provide?
A detailed adaptive interview, record review, a persistent 90-day case state and an evidence-linked research dossier. It is research support, not prescribing or treatment.
