Hi!
I don't have MS but I have RA. I know it's like comparing apples and oranges, but they're still fruit. They're both still autoimmune diseases. I've had umm about six surgeries since my diagnosis and I've never experienced a flare from surgery. I do experience flares still occasionally, so it's not that I do not flare, but surgery never brings them on. My rheumy attributes my lack of flares to be that my RA is pretty much in remission. My rheumy is my biggest cheerleader for getting revision to RNY. She says getting to a more normal bmi will decrease inflammation and make my disease even milder. She says if I do flare after surgery, no problem, she'll just administer a steroid injection.
So your neuro cleared you for surgery, they must feel that the benefits of the surgery will outweigh the risks. If you have any doubt, schedule another appointment with your neuro and discuss it with them.
Has your wls surgeon okay'ed you for continuing the celebrex after sleeve surgery? I stopped mine after committing to revision to RNY. I had to know I could survive without it forever.
I wish you all the best!
