IT could be a lot of effects of the rate/aspetic meningits complication.. I for me with the initial loading dose, i had such a bad meningitis that it was hard to tell what part of me may have been helped by the IVIG, and what part was weak from the meningitis part.. the 2nd round of IVIG was a miracle!!! I started to get upset it wasnt' going to work, and then I awoke on day 4, and i felt cured!!! Could actually even smile (which I hadn't been able to do in forever).. we just went at a MUCH slower rate after that first go around.. and had much better luck.. but of course everyone is different! sorry your not feeling well, I hope they figure out something to get you feeling better - and that will work treatment wise!!
