This is my first post and I would really appreciate your advice.
I'm seeing my doctor on Tuesday and was wondering how best to approach discussing B12 deficiency/Pernicious Anaemia, eg should I be asking for particular tests?
I've been suffering with really bad fatigue for the past two years now, to the point that i've had to give up work and have a non-existent social life. I've had various tests done but the doctor hasn't been able to pinpoint a cause. I've also found that my concentration and memory are very poor, I often feel very weak or faint and my muscles feel weak too. I had my B12 levels measured 6 months ago and they were 207pg/ml (197-771). As it was in the normal reference range I left it at that but more recently I've been experiencing other symptoms like heart palpitations, a rapid heart rate and a tingling/twitching feeling in my arms and hands and wondered whether this could be related?
Any help would be really appreciated.
