I wish you only the best .I've only been diagnosed since mid Sept . but this forum has provided a wealth of info to me ... I'm not knowledgeable of plasma exchanges and IVIG procedures but I do know that when you're hurting you seek relief ..
Justdeb gave some wonderful advice to you and I really appreciate her words of caution ... I'm beginning to see the ups and downs of MG ....two weeks ago , I thought that Mestinon had me totally under control ..Last week ..Bam !!!!
Keep us advised of your progress and we're all there with you
