Loose stools that are driving me crazy

 my bowels and gut hurt so bad. I don't want to do anything. I finally do get up a little energy and go eat and bang it is on the pot. Soon as I eat about 20 minutes I have to run to bathroom. I hate this I know where every bathroom is in Ohio. I can't even go to grocery store if I have ate first. It is do all the things you have to do before you eat anything. I can eat noodle soup or pizza and I get the same reaction. I have had IBS for about 15 years but this time it will not go away. It has been since July since I have seen a solid stool. Never in my life thought I would be so happy to see that but I am telling you it would make my day. Does anyone out there have a clue as to help me get my wish. It hurts so bad and my lower belly is so gassy and under my breast bone it is huge like pregnant and I am 59 so no way. Please help me try to figure out this sore belly and gassy gut and the loose stools all the time. Even when peeing I get a little loose stool  

yes I had a colonoscopy in 1999 and all was fine. I went back last year and he wanted to do the test for checking the stomach and it was fine but I sure have trouble. So I went to the office to talk to him and you know the procedure it is see you in Nov 30. My lower bowels hurt and get so sore and my upper stomach gets so gassy and swollen. I really do not know what to eat.I get the problems even if I eat rice and try to be really good it acts up the same way. So far nothing eases the problem as far as food. It all causes the same action. Eat and run that is my life.
