Hi all I'm new to the forum. Have been suffering exhaustion, disorientation, pins and needles in hands, weird salty taste in mouth, tinnitus and an odd breathless feeling (keep sighing) and have seem to be losing my train of thought/forgetting the odd word. Dr has done full range of tests inc FBC, viral (she thought it was post viral fatigue) and b12 and all are "normal" with no anaemia. It was only when I queried that my b12 level was right down at the lower end of the range (215) that she agreed to try me on loading doses of 6 over the course of 2 weeks then 3 monthly. She still doesn't think I am deficient but at least is treating me. My question is whether the dizziness/disoriention, tinnitus, pins and needles and forgetfulness are classed as neurological symptoms? If so should I ask for extended loading doses? I just want to feel normal again!
