I an a sufferer of IBS C for 12 years and I am only 26 years old. I pretty much gave up on life and only had one choice left. The colonoscopy was my last resort and the test came out showing a normal functioning intestinte. I wanted something to be wrong to prove I was not crazy. Now it is the day after the test and I am in more pain then ever. How do I explain to people that all this pain is all in my head?
