My colonoscapy was the most pain i have ever experienced. I had sedation and quite honestly I've had more pain relief from a single paracetamol. Not even three labours, my last baby waz 9lbs came anywhere close to this pain. I would never have this procedure again. I was told after the colonoscapy that i had extreme loopy bowel, so perhaps i was just unlucky. But on a happier note nothing sinis3was found
