Hello - I wonder if anyone can help me - I am confused about all of this.
I'm in the UK - I went to my GP recently, saying I'd been feeling stressed at work, not sleeping well and suffering from fatigue. I've had fatigue in the past since having testicular cancer a few years ago, and have been on replacement testosterone therapy since - one of the symptoms of low testosterone is feeling fatigued, and lethargic after meals etc. I thought basically I maybe needed a good rest as work had been crazy for a few months. I'd also been having palpitations but I attributed that to feeling stressed.
He ran the usual blood tests, 'not expecting to find anything unusual' but a few days later I was called by the GP to go in and discuss the results. I had assumed it would be about my cholesterol.
He said I was low in B12 (194) and whilst still within range, this wasn't normal. I didn't really know what he was talking about as this was all new to me. He prescribed me 2 ampoules of 1mg Hydroxocobalamin, one of which I was given by injection the following day, and the second one 7 days later - it is now 10 days since the second injection.
For the first two days after the injections I would say my sleep quality was better, and I felt more refreshed...but apart from that I don't really notice much difference. Should I?
I don't have the other blood test results to hand but he distinctly said that I didn't have pernicious anaemia as my intrinsic factor was fine, and that my full blood count and iron was fine too. A previous routine blood test in 2013 had shown it to be around 350 (i think) so it has dropped over the past couple of years. I eat a full diet, no medications have changed, and the doctor said it was 'a mystery' why this was happening. I am due to have my blood retested in a week's time. I am age 44.
Can anyone suggest what might be going on? Is it something I should be worried about? And am I anaemic - I thought up to now anaemic related only to iron? I am confused by all the info out there.
Thank you for any advice.
