Hi. I have frequent dizziness problem which occurs after little workout or even a walk. All heart and brain related tests including MRIare normal. My
B12 was 228 in 2019 and I took injection shots but symptoms reppeared after few months. In June 2021, again the B12 levels dropped to 137. How do we differentiate whether this dizzoness is caused due to anxiety and stress or due to B12 deficiency and absorption issue. Please help
