Hello, I'm so grateful for this forum and all your amazing knowledge and advice. I posted some results a while back and clivealive gave a very helpful answer (Thanks clivealive!). Sorry if this is a long waffle, but i'm feeling desperate and could really do with some advice about my new GP practice.
I was diagnosed with a B12 deficiency about 3 years ago, and although the pernicious anemia test came back negative, after going through my diet and the fact i was taking B12 supplements at the time, it was decided it must be an absorption problem. So I started on injections every 12 weeks. These eventually increased to every 6 weeks at my next surgery due to my symptoms coming back at this stage.
At the beginning of this year i had to change surgery. They insisted i had a B12 test straight away (6 weeks after my previous b12 injection) and it came back with a B12 level of 750. The doctor told me i was cured and no longer needed injections!! I went back with symptoms and had private tests done about a month later and levels were 550, so injections were refused again, but my vitamin D had dropped below normal levels again for the second time in a year, so luckily I was treated for that.
I went back again about 6 months after my last B12 injection with horrendous symptoms (really bad depression, panic attacks, paranoia, frequent migraines, burning sensation in hands, pins and needles in feet, weak legs, exhaustion, dizziness, yellow skin, constipation, confusion, memory problems, brain fog, difficulty concentrating) and was given another B12 test, this time it came back at 350. They reluctantly let me have a B12 injection (no loading dose etc) and the symptoms eased. They tested again for parietal cells and intrinsic factor (a week after my B12 injection - could the B12 have skewed these results??), but the lab came back and said they had refused to test the intrinsic factor because the parietal cell test came back as normal - Does anyone know if this is standard practice??
i have now been informed that because they have recently identified a patient who had B12 injections for 10 years and whose results were off the scale (over 2000 and sometimes un-measurable) that everyone on B12 injections at this surgery will have to have a blood test EVERY TIME their B12 injection is due, to see if an injection is needed. Having read on here that it is completely redundant to test after injections have started, i can't see how this is going to work!? I'm absolutely desperate because when my levels only fell to 350, i was in a complete state, couldn't do my job and almost lost my relationship, i can't go back there again!!!! I would be extremely grateful for any advice any of you might have. Thank you so much x and sorry again for my rambling.
