Can anyone give me some advise/information? I just received blood test results this morning for Vitamin B12. Range is 180-2000 ng/L. My result is 306 which of course, since in range, is deemed to be okay but I think that's quite low! I'm experiencing muscle ache and pain in hips, gluts and legs (hamstrings & groin) and now it's moved into the neck and shoulder area. Could this be because of low B12?
I also had low vitamin D, range (25-170). In March 2012 it was very low at 14 and in August after supplementing had gone up to 103. After a period of 6 months or so of not taking vitamin d, I'm supplementing again. I'm on 100mcg of levothyroxine (hypothyroid for 13 years) and have a referral to see an Endo (prob in 6 weeks or so) as I'm not happy with my TSH results coming back "normal". In December TSH was 0.36, January 4.1 and in March 2.0 (range 0.2-4.5). I know that should be at least at 1 and have been feeling rotten for some time and have been asking for T3, T4 and Reverse T3 tests but of course since the TSH is within normal ranges these are impossible to get. Anyway, just looking for some thoughts on the vitamin B12 issue.
