Well, just because the neuro SAYS it isn't doesn't mean it isn't.

Most drug reactions never get to a doctor, for them to see. Also some doctors will deny a drug's involvement consistently.

And finally a doctor's OPINION is just that, an opinion.

So the few patients who make it to the doctor, will be extreme and persistant, and few. There are some MRIs on the net showing demyelination in the brain, white spots on the films from metronidazole. These extreme patients were severe and on the drug a long time.

There could be another reason for your findings. The skin biopsy is rather new out there and not 100% understood. And you have only had the one.... it would be interesting to have another down the road to see if there are any changes.

I went back to your earlier posts. What did you take the metronidazole for? It is possible that the infection itself was the culprit, and the drug is just clouding things.

Did you ever take steroids to see if they dampen your symptoms? This would be a good test to show inflammation, which if they work, could point to using the IVIG then.
