I'm struggling with my GP and B12... I was diagnosed as deficient about ten years ago and have been having quarterly jabs. I've also had lots of 'mystery illnesses' including some problems with my bowel/gynae (they can't decide which), mental health issues (depressed, but now on all the antidepressents and still can't get out of bed). I'm forgetful, weak as a kitten, clumsy and feel sort of fluey at times. I've had constantly bad sinuses (which were operated on) and now have constant sore throat/earache/sore tongue.
My last jab was two weeks late and the days leading up to it I just slept! I could barely lift my shoes to walk, my fingers were tingling, I could see stars, couldn't get enough air... It felt like the gravity had been turned up and the oxygen turned down!
I went for my jab and asked the nurse to check my levels as I was feeling some pretty extreme symptoms. She asked the doc and he said no as my previous serum level was 395. But this was six months ago and two days after a jab! Surely if three monthly jabs were enough I should have high levels, not borderline? Especially if I just had my jab? So I had my jab and the nurse made me an appointment to see the GP the next day to be retested as she agreed it sounded off. I spoke to the GP who said that 395 was fine, but they would need to test me before my jab to get an accurate level so I'd have to wait three months! I asked her how a level taken straight after a jab was taken as accurate, but one taken now, straight after a jab wouldn't be but she had no answer. I then suggested that, as my levels were questionable, I had symptoms, was already prescribed B12 jabs and it did no harm to have 'too much' that maybe another top up now would negate the need to feel like this for another three months if it worked, and if it didn't we could spend that three months trying to find the real problem. She got cross then!
So I'm confused about where my levels should be. It was my understanding that the first set of weekly jabs should get your levels up to and beyond 'good' and that the quarterly jab should keep this 'good' level topped up. In fact, as I had been so poorly when it was diagnosed (serum level of 11) my levels should be 'high' to help healing. I've also been led to believe that your levels would be 'high' after a jab, and then be 'ok' by the time of the next one - sort of like recharging a battery when it gets to half power rather than letting it drain completely. So if just after a jab my level was 'just about ok' if you take into account a margin for error, then it must be at 'not ok/low' by the time my next jab is due?
I feel I need a top up, more regular jabs (monthly?) and a proper review in six months. I feel utterly dreadful! Any ideas of what to say or why my levels might show borderline?
