Brief history - I was diagnosed with ME/CFS 6 years ago (may or may not be, B12 104 at that time) but in June this year my B12 test showed quote from lab "had trouble finding any at all". I had 5 loading shots, no change for 1st 2 weeks then bit of improvement for 3 weeks then downhill. I now feel worse than before the loading shots but think I need more (thanks for all the replies & great info in response to my previous post. My GP still refuses any further treatment so have found a private GP who will (hopefully) give the injections but wanted to do his own tests first. He retested my B12 & it was 223. I know 8 weeks after loading shots is pointless as it will show high levels regardless of symptoms but how can my B12 still be only 223 after loading shots? Any ideas please?
My folate is 8.5 & ferritin 22 (am trying to improve them).
GP is doing further tests but am hopeful he will give me injections anyway.
