I have been battling ongoing symptoms for the last 7 months. Brain fog, disorientation, daily tension headaches, muscle weakness, Hot flashes, diarrhea and fatigue to name a few. I have dont MRI's, Cat scans , ultrasounds and even a colonoscopy. All my blood work has always come back normal. Just the other day my doctor decides to check my B12, Ferritin, Folate. Below were my numbers. Could it really have been B12 the whole time? I read that the 300 range was normal. My doc gave me a B12 shot right away and has me on 1000 a day. I am 27 years old.
B12 - 348
