well maybe not "body builder" , but I did gain considerable size lifting weights a for a couple years, but I stopped last year when I got shoulder tendinitis...

you mentioned that b12 deficency does not happen over night. I certainly agree with that, but I would think my symptoms would be gradual, as the levels dropped. but my "burning" skin sensation came on rather quickly. Sometimes I wonder if low b12 is even the culprit... but I've had so many tests, and everything is coming up normal, except my b12 was at 260.

I've read other b12 suffer stories and mine seem so different, which is only reinforcing my concern. Have you ever heard of a rapid onset of symptoms that I had (and painful) and it be because of low b12?

I mean I am feeling better , the pain has diminished greatly since my last b12 injection, which suggests it was my low b12 level... but my crazy paranoid mind thinks maybe increasing my b12 is just "masking" the symptoms and there is something else going on. (I warned I was a hypochondriac!!)

does my symptoms sound typical of a b12 problem?
