My daughter has had bowel related problems also, but no blood in the stool. We went to a GI who just prescribed laxatives. GIs do not do a lot of colonoscopies, and I was disappointed this was his first step. She had a lot of anxiety and many complaints about nausea. She's only 19.
I took her to my colorectal surgeon, and he did a full colonoscopy. It was a HUGE relief. Now, neither of us are that worried about her symptoms. She has some kind of IBS type colon spasms which cause pain and stops things from moving. Fiber, probiotics, and stool,softeners make her feel much better. But stress and anxiety can cause bowel problems!! I suggest you go to a colorectal surgeon. They do a lot of colonoscopies so are more likely to prescribe one. You may want to talk to a doctor about getting some Ativan or something for your anxiety, also.
