I have muscle weakness fatigue, high cpk, cold intoletance, pains in my legs. I was tested for b 12 and came back as 2200. Not sure what test they used. I stopped taking my sublingaul b 12. Thinking it was the wrong test. What is the correct test and rages to know if you are deficient?

I am also low in iron and take iron supplements and hypothyroid and on thyroid meds. I just want to end this nightmare and feel better. I am also a vegetarian, if that matters. This may sound stupid, but I am certain when i take vitamins with any b in them my legs feel worse. Have not tested this theory on b 12 though. Any comments or suggestions would be appreciated. Thank you for your time
