Hi, sorry for your health woes. One thing struck me that’ I’d like to comment on - the medical food your Dr.gave you. When I first had PN symptoms the neurologist prescribed Metanx (a medical food requiring an rx) for me. Shortly after starting it my symptoms became much worse-pain, tingling and numbness in arms and legs. So I reduced it to 1x a day and felt better, then stopped it completely. It hit me later that he never even checked my B6, folate etc. before prescribing it! I think I was taking too much B6 which can cause the symptoms I had. Later on my primary care Dr. did do appropriate bloodwork and only B12 was low, not that supplementing cured me, but that’s something I DO need. So I learned from that experience.
