One of my doctors offered me either rituxin or IVIG last September. I decided to do the IVIG and it has helped me but not to the extent that I would like. I was rear ended by a car this past March and it seems to have exacerbated all my symptoms and wiped out a lot of the progress that I made with the IVIG. I am thinking about trying the rituxin. The potential side effects are very scary, but it also sounds like the potential upside is great. Any thoughts?
