I've been having problems I think of Partially blocked intestines with pain, nausea constipation with mostly diarrhea and soft bowel difficult to get out I haven't exercised for a long time and I know that exercise helps with bowel problems also without exercise I've been extremely sleepy everyday for the past two days I have had hard stool come out but still with some kind of difficulty and today I started exercising again and I had diarrhea again and I thought with exercising today I would have more energy but I seem more tired I have had a CT Scan and everything was okay but the GI doctor still wants to do a colonoscopy what would she be looking for on the colonoscopy since the CT Scan and also all my blood tests are normal if you can think of anything that I should be concerned about that will show up on the colonoscopy please let me know I am really scarred about going through the colonoscopy about being able to feel pressure or what ever during it since I won't be fully put to sleep like I want to be.
