Kind of an older post but I thought this would be a good fit.

I've been lurking for a few months trying to get some insight into solving my neuropathy. It started about 6 months ago as a burning sensation in my feet, which spread to my arms and torso and face. It's mostly pressure related at this point, so always worse at night. I am not diabetic. The neuropathy started after I developed hyperthyroidism.

Anyway, I also noticed that salty foods like salted cashews or corn chips seemed to worsen the pain. I tried an experiment with baking soda (1/4 tsp in 8 oz water) and also saw an increase in pain. I'm just now looking into sodium-related neuropathy and came across an article that talks about a sodium pump defect in diabetic neropathy.

A sodium-pump defect in diabetic peripheral nerve corrected by sorbinil administration: relationship to myo-inositol metabolism and nerve conduction slowing

Not enough posts for a direct link but it's a pubmed NIH document 2421135.

I'm wondering if anyone has already looked at this or has some experience with sorbinil.
