I had a colonoscopy done in October after having some bad abdominal pain and finding out I had diverticulosis at the age of 27. My grandpa died from colon cancer, so my dr recommended I get checked. I was so nervous to go through with the test and that they would find something bad. I am glad I went through with it though, they didn't find anything, and now my mind can rest. The test itself you aren't awake for, the prep is pretty gross, but I made it through it without throwing up or anything. If the test is something you think you need to do, just do it and get it out of the way, you will be glad you did.
