I've had many rounds of ivig and after a while they just stopped doing anything for me. We then went to cellcept but i had an allergic reaction to that. My neuro who is one of the top at emory university sent me back to my primary care doc for treatments that he said he could handle. He did advise me to come back to him if i became parylysed. So my primary doc writes all my scripts. My primary complaints now are all pain related. I'm lucky that my doc will experiment and write for those meds. It's not a perfect situation but i trust my doc and he has seen me through some hard times and knows when he can't handle a problem.
