I would massage to help with gas or elimination, lower R, up, across, down to lower L and center over the pubic bone. Repeat.
When I was in a flare, unless I was on the toilet I was afraid to touch or move my abdomen. Which was basically the last 5yrs before my surgery 5/08. I couldn't bend over, lean forward, reach to change the radio station in the car or for something in the glovebox, tense my abdominal muscles and even eating/drinking elicited an immediate response from my guts.
Since surgery, I'm doing much, much better.
