Ok, i know most all the symptoms of IBS. But, i have a question: Can some people's rectum be more sensitve? Like, when there is stool present? Every time there is even a dime size amount of stool in my rectum, i can feel it, and it irritates me!!!! Also, in the morning, i have a decent BM,as in no trouble coming out, then in the late afternoon i feel like i have to go again, but it just wont come out. I know i have to go, but cant get it to come out. any remedies?????
