Hi purpleorc!
Welcome to the site!
I have two friends with MS. One refuses to exercise at all, and the other began training in martial arts and has her own academy now as a second degree Black Belt! I known that there are MANY stages and many ups and downs with MS. I also know that every person reacts differently to it. It can't hurt to eat well, to add some exercise which will make you stronger, and to keep a positive frame of mind. My first friend gave into the disease, and my second friend chose to battle it with punches and kicks! She feels GREAT most of the time and credits the mental as well as physical toughness that comes with martial arts training as a real saving grace for her.
