hello
I have some of the same problems, meaning the reflux symptoms. I have mostly sensory polyneuropathy and small fiber neuropathy. A couple of years ago my GI doctor sent me to another GI doctor that specializes in GI related autonomic neuropathies. I had the manometry study, it showed extreme acid reflux. I have to, just as you, fallow the diet, and take Proton Pump Inhibitor medication. I had the gastric emptying study, showing gastroperesis.

My neurologist said this is related to autonomic neuropathy and therefor also related to SFN.
I would rather not take the meds, because it inter fears with absorption of a lot of nutrients. But for now, I have to take it. I have tried to reduce the dosage.

How is your SFN symptoms otherwise?
