Does anyone get pressure feelings when the gas builds up so bad. The pressure feeling seems to radiate right were the hip meets the thighg and radiates down. My theory is that the pressure causes some pressure on the nerves, in other parts of the body. Thats my guess, I am only an accountant to be one of many like you who have been told after a colonoscopy that nothing was wrong. I was hoping something was wrong like diverticulitis or something. To be told nothing when these symptons are very real, well you know. IT IS VERY FRUSTRATING.
