I have just had my first ever colonoscapy and I pray I never need another one.

I opted for sedation, thinking it meant general anaesthetic.

I was given Fentanyl 75ug and Midazolam 2mg both administered intravenously. 

 I too was told that the procedure would be uncomfortable but not painful.

 As soon as they started the procedure the pain began, It was so excruciating that I ended up begging for more pain meds, I was given an extra IV painkiller then entonox too.

 At one point I ended up yelling in pain at the top of my voice, they stopped briefly then restarted, informing me that I had a loopy bowel. I can honestly say that I have never felt pain like it in my life even though I have broken ribs, fingers and even broke my upper jaw in a car accident.

 I persevered for as long as I could as I really wanted the full procedure but eventually the endoscopist stopped the procedure saying that all the noise I was making was too destracting and that I was obviously in pain.......

 I too was made to believe that I was an awkward patient and overreacting.. 

 It's good to see that I am most certainly not and I think this must be the norm....... So why do they all lie in saying its nothing more than discomfort,(like trapped wind)?

On my report I saw that they found I had a tortuous colon (a colon with a lot of tight bends in it) and that the scope was retroflexed in the rectum...

Absolutely  traumatic experience.
