Hello I am fairly new to this forum, although reading posts since last June. I have responded to a few posts but am really in need of advice. I am 64 . I was diagnosed last june with b12 deficiency serum 165. Although I had many symptoms for several years, vertigo, restless legs, palpitations, the fluid behind my eye changing density resulting in thick black wavy lines, floaters, Electrical shock feelings in hands Mentally getting into a very dark place, memory loss brain fog. . None of these symptoms picked up as b12 deficiency by my GP. Not until my feet got to the point that they felt stuffed with cotton wool and tight bandings round ankles that I could barely walk did I start to investigate and finally asked for b12 blood test. I don't have PA. I had initially been put on loading dose then 1 injection 3 monthly. . I saw a neurologist and was prescribed 1 b12 injection weekly. I have also been self injecting, at least my partner gives me the injections since last December a further 2 times weekly. Sometimes I feel a little better but the cotton wool feeling never fully goes. Sorry for rambling, but I feel I am loosing the battle as I feel little improvement. These last few weeks I have started to have fluttering under my left breast and am really worried, although I have had palpitations in the past, had ecg, which was fine but these are new symptoms, also sore tongue and ulcers have returned. I suppose I am looking for reassurance I don't know anyone with this condition, my GP has little knowledge of it and I now feeling desolate and in the wilderness. I eat well my folate initially 6 it is now 12, eating really good diet, potassium 5, ferritin I think 60, not sure. Should I feel more improvement with so much b12 after all these months and is it safe to keep taking 3 injections weekly. My other worry is that even with all this b12 could I be getting worse. Without reading posts on this site since last year I would have been totally lost. Any help appreciated. Thank you.
