Mine was a hundred times easier than I thought it would be. I decided to go without anaesthetic as I wanted to be able to go home straight away afterwards. A good friend had done the same and was encouraging. It was uncomfortable but painless. Odd and weird but over sooner than I had expected. The medical staff were superb. If you have a sore bottom after the many loo visits caused by the night before concoction, you can ask for a soothing gel to be applied first. If you are really stressed you can opt for an anaesthetic. In my case they were prepared to use anaesthetic at any point during the examination if I felt stressed. I had 2 nurses in attendance, one watching the doctor and the monitors, and one watching me.
Whatever the results, you are doing the exact right thing. You’ll either be clear of worry or put onto immediate treatment. In my case, the rigorous cleanse seemed to clear up my problems!!
This exam is a great way to rule out serious problems and help your GP diagnose the issues.
