Hello: I have the exact same problems. I think it is related to my cycle and lasts at least 2 weeks every month, if not more. It is uncomfortable,sometimes painful and embarrassing. Food doesn't seem to be the cause. I have been taking probiotics for 3 months which has helped but not alleviated the problem. Taking Advil actually helps because I believe it can be related to progesterones which is another hormone that affects the muscles in the lower stomach. I have had several medical tests and been on different hormones(birth control pills and Depo shot) and nothing shows on any test and nothing seems to help. Good luck and I will keep looking for an answer.View Thread
