I have been reading the board and my symptoms seem so different from many. DO I have IBS? First of all, I don't have constant IBS or constant D or constant C. It alternates along with the shape/consistency/color of my bowel movements as well.I get really bad D at times (used to be a lot more often). An urgency to go and then tons of D and sometimes really bad pains in the intestines (?gas pains?)...sometimes I'm sweating and feel like my intestines might explode or I'm going to die. After I go, there is no pain!This usually happens after a holiday dinner. Sometimes after random meals. Used to be after I ate out. Often before my period I was C, then D once it started.I was constipated off and on- especially as a child- I used to cry during bowel movements and my sisters would try to help me by playing games with m e while I was trying. I notice when I am constipated, I then have VERY hard large stool which causes pain in my intestines. Sometimes I see blood on the tissue or streaking my stool ( have had two colonoscopies for the last four years ago and they didn't see anything each time). I had this three weeks ago and today- both after large hard movements.My IBS(?) not all the time, it's not the constant "ache" type pains others are describing...it's always been severe intestinal pain/twisting and then release at movement. Can large hard movements cause blood streaking on stool ( my gastro didn't seem concerned after coloonoscopies were clear).I am also wondering if some mucus that looks tinged with blood could be constipation related. Bright Red. I have had external hemmoroids in the past and the bleeding while having a movement was the reason I had the last colonoscopy that was clear.IS this IBS ? I'm 47. Thanks RIBS
