I was in the same situation about a yr ago. What I have learned about exercise is if is causes pain don't do it. For us no pain no gain theory does not apply. I know how you feel about the belly. I have a belly from steroids and IBD along with not being able to work on abs. I have cut carbs and watch snacks. I was able to loose some weight. It is frustrating to not be able to do the physicial activity. My advice; listen to your Dr. The only other thing that I can tell you from personal experience is to do light streches when lying in bed. That will keep you from getting "rusty". Best of luck.
