A fellow at our dojo just got his license for being a masseuse. At the school where he went they had a sign indicating a variety of people they could not serve and MS was on the list.
I use acupressure for my right eye pain, but I gave up on massages too. Do I miss them? You bet. But I do not want to have even one problem result. Stick with stretching and a low impact exercise (walking, yoga, tai-chi, modified pilates...) to be safest.
