Has anyone here had surgery since being diagnosed with MS? How have you done? Any issues arise?

The reason I am asking is that I spoke to my neuros triage nurse this afternoon and the doc is worried about a possible exacerbation after I have this by-pass surgery done. He wants to coordinate with the surgeon to get me on either steroids or IVIG immediately following the surgery. I'm thinking..."WTF??" That makes it sound like the exacerbation is a given following a surgery??!!??

I had a major exacerbation last April and in the last month or so have finally realized a vast improvement in many areas, most especially my memory. This is one of those...durned if ya do...durned if you don't situations. I don't want another exacerbation! This one was a living H-ll. I don't want to have to take steroids again and I never have had IVIG and the only thing I know about it is it is expensive. (yeah yeah I know I can look up info on it and I will...) But I really have no choice in the surgery. If I don't have it I will continue to have unbearable pain when walking and risk having a stroke.

I hope someone out there has experienced surgery and has some advice for me. TIA!
