One of the reasons that the doc always tells you to lie down and take it easy when you are in pain---is because he/she wants the colon (large and small bowel) to settle down, rest, and become as still as possible.
I love outdoor exercise, but have virtually given it up in the past decade. The only thing I do is to go to the golf driving range and slam those golf balls! (good therapy.) But even that always leaves me with a a small uncomfortable blockage later on. It's the bending over--- I have to BEND at the waist, to pick up the ball and place it on the tee, etc. I went to the range yesterday, but could feel it coming on after hitting only half a bucket---so I ended up giving the rest to the person next to me. Any repeated bending is a sure trouble starter for me.
