  • Hi npno,

    The very best place (in my opinion) to get advice and support on Pernicious Anaemia is the Pernicious Anaemia Society:


    What country are you in? Can you read English very well? You can read a lot of information on their website for free, but to post your story on the forum you need to be a member. There is a fee of £20 for membership.

    They also have a Facebook page:

    Although they are UK based their membership is global I think.

    Are you feeling better since having the injections? Don't worry about your B12 levels, as they will be high once you've started B12 treatment. Any excess that your body doesn't need is passed in your urine (it is a water soluble vitamin).

    I don't know about your sore mouth, have you had your folate levels checked?


  • Have you seen this page?
