I am due to have a colonoscopy in 6 days and my anxiety is through the roof. I have been passing a lot of blood so do understand the need to investigate, however, due to problems with my bowels I have had this procedure twice before. Both times the procedure was ended due to severe pain and the inability to get the scope through the bends as I have a contorted bowel. The thought of going through this again is really upsetting me. Any suggestions would be greatly appreciated
