I can relate. I started my first round of IVIG this Monday and went home feeling fine. Tuesday morning I woke up with a headache, nothing severe, and went to my second appointment. The first day I was there for about 5.5 hours, and the second day they said because I seemed to handle it well, they decided to do it in 2.5 hrs. MISTAKE. The migraine was so intense I couldnt move; and the nausea...oh man... When I got to the ER they did a million tests and gave me something to help with the pain. My doctor said I could cancel the rest of the treatments that week and just stay home and rest. Four days later and the headaches are finally gone, but now I've got weird tingling in my hands that I've never had before?
I know for some IVIG is a real life-changer, but after such a horrific experience Im not sure I'll be willing to try again.
