I'm 19 years old, male. My
Vitamin B12 has been at a level of around 180 ngm/l for the last 6-7 months and
Vitamin D at 8.3. I was having severe headaches, body pain, loss of cognitive skills and unexplained fatigue. Only after 7 months have I started medications for Vitamin B12 and D. What is the probability that my neurons have suffered permanent damage?
