Multiple Sclerosis & Tummy Tuck/Breast Lift?

I have had MS for 11 years and only 2 relapses in that time not counting the one that lead to my diagnosis. I'm 33, work out 4-5 days a week and eat healthy. Is there any contraindications to having cosmetic surgery? My surgeon is aware I have MS and he plans on doing 2 separate surgeries (tummy tuck and breast lift first) and 6 months later an augmentation. He will only go forward if my specialist will give approval and she refuses. Should I see a new neurologist for a second opinion?
