Thank you for your response:) My B12 range was okay (425 and the normal range is 230-1,050), but maybe I should start taking it cause it can't hurt. I have had CBC checked a few times over the past months, and nothing stands out just a little high for RBC and hemoglobin. Iron is normal but on lower end. Frustrating since I'd think with my extreme symptoms it would reflect in my bloodwork, but all tests are coming back normal. I try to stay consistent with PT, but sometimes it leaves me more sore and wiped out than before. It really is a delicate dance, and even more tough when no one knows what's going on.
