One thing I forgot... My husband had one for his Crohn's diasnosis last year. Since you are having issues you may experience some pain/discomfort afterwards from the air. We had to find out what additional pain killers he could take because the pain continued after the meds from the procedure wore off. He had a lot of inflamation from the Crohn's, so this is probably not the norm.

Kudos to everyone for taking care of your health. My Pawpaw had colon cancer. My dad is in remission from colon cancer and it broke my heart to have my stepmother in law tell me she would "never have another colonoscopy because she can't think of anything worse". Well I can and have seen it.
