My pain started 7 years ago. Since then I have seen many, many, many, doctors and healthcare providers to try and find an answer. Unfortunately no one had any ideas and only wanted to put me on antidepressants to "mask" the pain. I have read some of the blogs here and feel the same way about the medical field regarding PN. I have burning sensations that started with my reproductive area and then spread to my feet, my hands and now my TONGUE! It has only been recently that I started researching B12 and have had some improvement. Does anyone have experience with diet? It seems that when I eat Processed foods I have an increase in my symptoms.
