My hemotologist mentioned that maybe the IVIG was working because I was standing in front of him, and not limping or using a walker, etc. I took that into consideration, but then freaked when I got the one automimmute test back that suggested thrombosis. Then I got in a big argument with them, which is a long story, but the receptionist assused me of picking up my pain meds and taking them to another pharmacy and coming back for more, when I went to pick them up for the first time! I cancelled all the appointments with them, and never went back. It hurt really bad because it is already hard, but I know the difference between dependence and addiction, and they were accusing me a lier. Anyway, if I do start IVIG again, I will have to find another hemotologist to treat me
