I attempted to do the IVIG for my MG one week ago. After the third day had a very negative reaction and they stopped the procudure. The doctor said I was having anaphalatic reaction put me on steriods and I think predisone. What I still have is one or two times a day very intense feelings in my upper chest, almost like fluttering or like I have had 5 monster drinks. Anyone else ever had this and in general what were your post procedure results or experience. Thanks
