hello there, well for the last 6 years, since i turned 18 iv been getting extreme dizziness, dizzy spells, balance problems, nausea, vertigo, cant sit up or stand up straight for long without feeling like im going to faint, plus loads more and after numerous tests like mri's, ecgs, eeg, balance tests and ear tests etc but all were normal. i decided to get my b12 tested as i match all the symptoms and its never been discussed. How is this b12 level? what do you guys think, could it cause any symptoms? b12 222 pg/ml 197 - 866 folate 4.8 ng/ml 4.6 - 18.7 ferritin 44 ng/ml 30.0 - 400.0 . Why am i always borderline lol? iv just started my methyl b12 lozenges 1000 mcg as i highly doubt my GP will give me injections, what should i do?
