I joined the PAS and this forum at the beginning of Sept this year having been diagnosed with PA in May 2013. I hadn't received any loading doses and was put immediately onto 3 monthly injections. My readings on each subsequent visit to the Doc were around the 200 mark. Thanks to the forum I realised that the numbness and burning in my feet and burning skin on my right side may have been due to B12 deficiency and not diabetes as I thought. At the start of Sept I had Blood taken before a minor knee op and the B12 reading was 575 that was 2 weeks after my regular dose.
So November comes I'm still off work so go the doc early get blood taken and a week later go for the results. B12 293 bearing in mind this was two weeks early. 'You're B12 level is OK' says he, 'Oh no it's not Its too low' says I 'and I have neurological symptoms' explaining the burning etc. I told him that I had joined PAS and that at no time did I want my b12 level be allowed to fall below 500 at worst! He then put me on 2 monthly jabs.
Success! I had my dose that day.
One week later I get phone call from surgery stating Doc wants to see me and to book a double appointment which I did. I spent an hour with him and he went over all of my symptoms right from the start and had a complete medical. The upshot was that I got another jab the next day and am now on 1 monthly.
At this appointment he went through some of the original test results when I asked him if I had PA. He told me that a Parietal cell antibody test proved 'mildly positive ' but the IF antibody test was negative but 50 percent of people negative for this can still be anaemic. So none the wiser there.
However, the point is get more info to back up your case tell the you're in the Society and it might help. I don't know what he did or read bring about his change of mind but I don't really care.
