Hello! I'm from the US, hope thats ok.
I had my blood drawn 3 weeks ago and my B12 was at 190. I started daily imjections for 5 days. Now I am on a weekly shot. And I dont think its enough. I'm not due for another shot until Wednesday and Monday I started feeling fuzziness and imbalance again.
I dont know WHY my B12 was low. My D is low as well. What other testing should I request?
