Well I thought it was all going too well. After reading on here the importance of having a full blood profile done and ensuring that as thyroid suffers, we convert thyroxine better if our ranges are in the upper levels, I went along and asked my GP for such a profile, no problem, he agreed! The results have come back (he didn't do the ferritin and folate) but the Vit D3 is 33.000 nmol/L (range 25 to 50 nmol/L = insufficiency) so he advised buying some OTC tablets which I have and have started taking them. B12 results were 286.000 ng/L (range 200-700) as I have symptoms of itchy skin, lethargy, joint stiffness, gut upsets, blurred vision, pins and needles in fingers and walking into things, with my result being in the very low edge of the range I asked for B12 treatment. It was made very clear to me that whilst my results were in range, it would not be medically ethical for him to support treatment with B12. He dismisses my symptoms as just getting older and I have to accept it. I wanted to mention that I believe my Mother had pernicious anaemia (I remember her talking about it as a child, but back in those days no-one ever really discussed their health and I remember her being very tired and pale and she died of breast cancer aged just 64 which they say she had had for a very long time before diagnosis) but his attitude put me right off. I wanted to cry, it has rolled around in my head all night and I have hardly slept, could still cry. He told me that he had looked at the Thyroid Uk site and said it was 'quack garbage' he was just rude but trying to be funny, if you know what I mean? I tried to say that whilst he/the lab keep trying to encourage me to reduce my dose of Thyroxine, perhaps if we tried medication for B12 and increased the level, then my symptoms might subside and I would then be happy to reduce thyroxine, but he wasnt listening. It all makes perfect sense to me so I cant see why he should be so dismissive, but I do not want to go back and see him, I think I will see another new GP to the Practice. Can anyone of you on here give me your advice? Shall I buy OTC B12 and start taking that and see if my symptoms improve?
