Reply To: now itching all over w/o rash

Hi,I had one round of IVIG in mid-dec. no problem during the treatment but 10 days later started to get rash. Dr put me on a course of prednisone but did not do much good. Have cortisone cream both 1 & 2% still have hives everywhere. So itchy and uncomfortable. What now ? How long will it take to go? Anyone out there who can give me some advise, much appreciated.
