It looks like I will be starting ivig - possibly next week. The first time I have it done I need to go 5 days in a row. I am a bit nervous and am wondering what to expect. For those of you who have gotten ivig, were you pretty miserable and if so, for how long? Should I expect to be out of commission for a week or 2? I'm most worried about a headache I guess. It was approved based on neuropathy, so it is not for CFS per se.
