I can only tell you of my own experience. 18 years ago one of many symptoms, I had burning feet. I had to put them in water or spray them with water and put them in front of a fan. They were never under the blankets even on the coldest night. I had B12 injections and since then I never had it again. Injections have been stopped and I have been told to take B12 tablets. It seems although tablets would not work for the past 17 years, because the CCG no longer want to pay for injections, I have had a miracle cure where tablets will suddenly work. However that is beside the point. I have been looking up about neuropathy and B12 and have found articles that say B12 helps neuropathy (even diabetic neuropathy), so it might be worth while to try and supplement with some B12 tablets, even though you might be eating plenty meant and dairy. If a vegetarian or vegan definitely look into B12. Give it a few months to work though. A lot of people have said they get worse for a short while before they get better.
