I am 59 and I have pernicious anaemia I have known and been doing B12 shots for a few years now. When I realized that this is what I was suffering with my number was 103 at that time I could not walk on my own I was in extreme pain, could no longer think enough to know how to make a good meal O and so much more I want to cry just thinking about it!!! I had been told I had MD for 7 years as my body was slowly deteriorating then the last year t got really bad I knew I was dying the last 6 months. Although I am doing much better now I will never be the same. also my daughter was having problems for the last few years she finely went for blood work and also has the same low B12 it was 137 she is having her injections every 2 weeks. she is 34 years old.
