Hi! I had scans done last week and one of my doctors (Quality of Life) suggested that I go on the South Beach Diet and do a 7 Minute workout video on You Tube for exercise. It's a cardio workout that when I did it yesterday has me in great pain today with sitting and walking..I know he meant well but I've gone from 208 lbs down to 190 lbs over the past 5 months and I cut out all flours, products containing yeast (it gives me open sores if I eat anything containing yeast), and for the past 6 weeks I did what he asked and didn't have any fruit..no processed sugar, allowing for a 'treat' if I want one, once a week. I was hoping that exercising even a little of this challenging video wouldn't have hurt me like it did..and now, I just want to return to walking! Any recommendations on what would be a good exercise regime? My scans showed my stage 4 high grade serous carcinoma (fallopian tube) and the stage 2 Non Hodgkins (all places) are below 8mm, with many small 2 and 3 mm nodules.
