Hi. I am a 37 year old female, 115 lbs. For the past 6 months I've been battling this problem. Whenever I have an excessive bowel movement within hours I get bad stomach pains. It feels like trapped gas. I've tried Gas-X, which worked for about two months, now it doesn't work at all. I have a bowel movement, I get stomach pains for like 2-3 days then I have a day or two of relief. Then, I have a similar bowel movement again, and the cycle starts all over again. Can you please tell me whats wrong?
