Hello,
i am not sure if you had your hysterectomy yet, but I have ms and I just had a hysterectomy jan. 15, 2004. I too was afraid that the surgery would set off my ms symptoms, but so far it hasn't. There is so resting involved (and required) after the surgery that I think it actually helps with your ms! I also called my neurologist and asked him how I would do and he said to me "you will do fine, good luck with your surgery!" I would suggest that you call your neurologist and see what he/she says.
So, I speak for myself here, but I found that I am doing fine with no ms flare-ups. I am on rebif and I have had ms for ten years now.
Good luck and let me know what you decide!
Gail
