could a b12 level of 407 cause minor symptoms?
Have had minor (I emphasise *minor) tingling in my hands and feet, for years, but a flare-up recently, and some more recent tightness in thigh and right arm muscles off and on for a week. While I am going to see a neuro (and pray daily that I don't have MS), my PCP had a B12 test done and it came back at 407.
While it's not "low" per se, could it be just low enough to cause some minor symptoms? I also get a lot of cold sores, more than I used to and that can be a sign too.
Since I do eat meat (too much if anything) AND take a multivitamin, I'd think my B12 levels SHOULD be much higher than 407.
