Hello Everyone, I am in need of some advice because my doctors seem to not know much about B12 deficiency recovery. I want to know if anyone else is going through what I am because i'm starting to wonder if I have the right diagnosis. It all started in December 2014,I started experiencing nerve pain behind my left knee then within a month it moved to the right knee, then the right foot began tingling, followed by the right hand. Then within 2 weeks I was so fatigued I could not stand long enough to wake up my children for school in the morning. I was given a brain MRI which was norma and a ton of blood work. The only thing the neuro came up with is my B12 level was 280 which is the low end of normal. My regular doctor started me on 2000mcg of b12 pills every day. My B12 level raised to 1000 within a month. I have continued to experience strange symptoms since, it has been almost 4 months now. I am no longer as fatigued after one month of pills but, the tingling has changed and I feel numbness almost all the time now on the palms of both my hands and bottom of feet . I experience occasional muscle twitching and even some ringing in the ears, even nerve teeth pain. The nerve pain behind the knees still comes and goes every day, I really don't feel like any of the nerve issues are getting much better. The Neuro told me the other day that it could still be B12 but, I am worried I have been misdiagnosed. Has anyone else experienced anything like this? I would truly appreciate any advice. Thank you for your time.
