I,also have lower abdominal pain. Mine, I don't think is related to gas or my intestines. The reason I say this is, my doctors have run all the tests. MRI,lower GI tests, still are. Friends suggested acidophylis and bifudus pills and they cleaned all the yeast out of my system. Ouch! I used to eat a lot of yeasty foods like breads, pizza, cheese, etc. I don't have much gas anymore and my complexion has really cleared, so the probiotics helped me, might help you. Good Luck. Does anyone else have any idea? I had a hysterctomy years ago, and the doctors checked my appendics too. I hurt all the time now. Any reasonable suggestion might help. Thank you
