I was given 5 days of IVIg and released. Now I'm trying to decide if I need to seek more tests in case it ISN'T Miller Fisher. Thanks for your help. Sorry to hear about your symptoms, I realize they are very scary. We have seen this in our practice.
Most people recover fully.
Recovery is very patient dependent and is related to the degree of the symptoms. So, it is difficult to give precise answers to recovery time. I would tell you that if symptoms reoccur or if new symptoms occur that you should begin to question the diagnosis. If you keep getting better, I would say that Miller-Fisher is the correct diagnosis. Maybe an EMG might help clarify matters, but really I wouldn't recommend one unless things change for the worse.
