i have had my second IVIG INFUSION. after the first one i felt very tired and thought I would just go to sleep for a while. However I felt bad for several days after. They told me at the hospital that this was just coincidental. Now I had the second infusion and I felt even worse. Initially very tired and then my blood pressure dropped and stayed low for more than a day. I felt dizzy, nauseated and extremely tired. Has anyone else had this experience?
