Hi, I'm newly diagnosed with low B12 (my result is 147, normal range 181-914). I have not been diagnosed with pernicious anemia, at least not yet--the cause of the low B12 remains to be found. I was tested because of tingling in my arms and legs and muscle twitches in my legs. I had 7 daily injections and have had one of 4 weekly injections. The tingling seems to have improved, but the twitches have not. They are small, brief and almost constant, and I now realize they are all over my body, not just in my legs. They're not painful. No one can see them, and when I'm active I don't really notice them. From what I've read, it may take some time for them to go away, or they may not go away at all. I'm just curious to know about others' experiences with muscle twitches, and whether they went away, how long it took, etc. I would also like to know how it can be determined that the twitches are related to B12 deficiency, and not another cause? I'm living in fear that the B12 diagnosis is a red herring and something more serious is going on, but I don't want to embark on an unnecessary round of visits with specialists and testing. I should also mention that my vitamin D is low, so I am taking vitamin D. Magnesium was normal at the time my B12 was tested. I would greatly appreciate input from others with similar experiences.
