I have been having stomach cramps and urgently having to rush to the toilet with D . This happens about half an hour after I have eaten, this is something new for me with my Ibs-D, its like I have pockets of wind in the tummy and they move, and it feels like I need to blow wind, but then the tummy startss cramping then I have to rush quick to the toilet. I take Colfac(meveberine) tablets before each meal, but they do not seem to be helping, my doctor is getting fed up of me going and says everything I tell is down to my Ibs-d. I am getting fed up of always going to her and having no luck. I feel very tender and sore around the left side of the colon. I have not changed anything in my diet so dont know why its happening. Any advice please.
