Hello all. My husband has had two treatments of the IVIG without any improvement. In fact he continues to get worse. Has anyone NOT responded to IVIG treatment, but responded to another form of treatment? With no response, I am wondering if he has MMN or something else...the worst case being ALS. He has no symptoms with his mouth...all is well. Please give me your feedback. Also...anyone with MMN that got so bad you had to be in a wheelchair? Karin
