I have been having awful symptoms for about a yea, worsening as time went on. My pPCP, neurologist, and even bariatric dept missed this for months. I had gastric bypass surgery 10 years ago, so this didn't completely surprise me (B12 issues), however it was never completely explained to me the gravity of what that could mean. I ended up self referring to the Mayo Clinic because all I was getting locally is that I have migraines. 56 years old and never had migraine in my life until a year ago. My B12 was 180 but had numerous neurological issues. I received an injection in early May and 3 weeks later went to dr. And they ordered 2 injections a week for 3 weeks. That ended Friday. Today had my B12 tested and it was 1535, which is much higher - too high? I go back to the PCP on Wednesday, and I am afraid he will look at that level and tell me I am good for a month...I do know eventually I will be on once a month for life. What I do not know, is the normal routine to go from loading dose to monthly, or is it better to go to weekly or bimonthly to begin with? I am in the U.S.
Note from Admin: This post is now closed to further replies due to some unhelpful responses relating to cyanocobalamin. Like all forms of B12 cyanocobalamin doesn't necessarily suit everyone but some people do find it very effective
