Yesterday I went to visit doctor katz to get an ivig treatment despite the reaction I had. We changed the brand and pumped me up with pleanty of antihistimine and steroid. Everything went ok, my throat only seized up twice. For now I no longer have the luxery of being able to get home infusions due to the high risk of anaphylaxis. I desparately need treatment so Im willing to drive up to connecticut weekly if i have to. i would do anything to get well.
