My 80 year old mother has what she calls a "stomach ache" constantly. We've been to the doctor and er and they tell her it is gas pains. She had a colon resection 6 years again and takes a pro-biotic every day. Most of the time she has regular bm's. She takes simethicone or gas-x. We walk around and eventually the pain subsides. Has anyone had this problem or any suggestions?
