good luck with your second round - I could sympathize with you regarding serum sickness, it is absolute torture....but at least they could keep you on sol-medroled up a bit longer and maintain your Prednisone longer (fun!!) to avoid a second episode....I also react to everything these days with spontaneous hives ect. I think it is from all the antibodies circulating in our systems from all the platelets we've received....
I hope this one works for you
I hear the rabit is more powerful than the horse....
