I am a fibromyalgia sufferer and when my dad passed away suddenly the other new symptoms I had were put down to grief by my GP. As things weren't improving I went back and it was a locum. He took bloods and few days later I had a call from my GP to say I had folate and B12 deficiency and this will be a life long condition. I have now to take folic acid daily and yesterday stated the first of 6 injections. My mother has the same deficiency but they didn't think to check me for this. My great grandmother had pernicious anaemia. Does this run in families? Can fibromyalgia make this worse. I'm 52 I am a lover of all green vegetables and fish which I eat a lot of but I am dairy intolerant. I do occasionally eat cheese. Are these added factors?
