I'm glad I found this thread. I shall sit down later and have a proper read.

A blood test a few months ago found that I was anaemic, so they checked my vitamin B12 and iron. I was very deficient in iron, have been put on supplements and my haemoglobin is back in the normal range. Addressing the vitamin B12 has been a fight as no one seems to think it's an issue, especially now I am no longer anaemic. Since late 2014, I've had tingling and numbness in my hands and feet. I've been told I have carpal tunnel and tarsal tunnel, as a result of having rheumatoid arthritis. I disagree and think the vitamin B12 is the cause. My level was 174 and lowest end of normal range for my doctor's lab is 190. I went back 4 times to discuss it and they finally acquiesced and prescribed vit B12 tablets. However, I feel I would benefit more from the injections. I have gastroparesis and have difficulty absorbing medication. My gastro has advised that I take all meds in liquid or injection form. Still, my normal doctor refuse to believe that the vitamin B12 is the cause of my nerve problems.

I'm in the UK and cannot find anywhere locally that I can pay for them privately.
