I am having periods of severe dizziness/vertigo, tingling hands, memory problems, vision distortion,toileting issues (going between constipation and diarrhea), severe fatigue & weakness. I have had
b12 deficiency in the past (level 64) when I was
pregnant and was treated with injections. It feels exactly the same this time. Last yr my b12 was 175 and it was considered to be normal. Symptoms have got worse. No level given this time but gp reported it to be fine. MRI came back normal. Any ideas?
