Neuropathy started during a gout spell

Ok, my neuroaphy started during a gout attack. It started in my toes and spread to my feet and hands within a few weeks. I never had it before and the Dr. continue to say I am not diabetic. I was is good health up to that 3 week point never having it before. The treated the gout with Colchicine, steroids and allopurinol during the 3 week time. I have every blood test known with no direct cause. I have some RA factor but not enough for clear diagnosis of RA. Seen a neurologist and dont have permanent damage yet but have flares from food and sometimes without. I ate a single chocolate cookie last night and now my feet are on fire along with arms hands and legs. No DR can figure this out, seems like something attacked my nerves during the treatment. Can it be something attacking nerves and why can we not find the connection between sugar and the neuropathy. Anyone that has some idea i am open to anything.
