Same thing goes for a colonoscopuy (camera from the other end) Did the home test and it threw up something, so had an appointment for the test given quite quickly. Main downside is the concotion you have to have the night before to clear/clean the colon which makes it seem the whole world is dropping out of your backside
Had the sedation but the proceure itself was so easy on me. (it did throw up another issue though) Had a call only a couple of days later to say that all was clear - Result !
