10 years ago I was given IVIG for GBS and it worked about 90% recovery. This time CIDP I was treated first with high IV dose of steroids. I improved but 4 days later I was back in the ER. That time I was treated with IVIG, it worked for me much better then the steroids, with less side effects. I’ve been on IVIG treatment every 4 weeks for the past 6 months. I have made great improvement on IVIG, I’m about 60-70% from where I was before. For me it just takes time with the IVIG, but everyone is different.
