I was dx’d with GBS in 10/2010 mostly better now but I had some skin reactions to the IVIG. It started with bumps or blisteres on my hands about 10 days after treatment, and then the skin started to peel off. I used cortosteroids, and after about 4 weeks it completely went away. I am not sure if the cortoseroids helped or not. Needless to say it was very concerning at the time. From what I have read it is one of the possible side effects to IVIG but nothing to be super concerned about. I wish I had known about it prior to the treatment.
