Hello. I am so sorry, not surprised you are concerned. I spoke to someone at MacMillan who said it's a natural reaction perhaps due to our survival instinct. I cannot comment on anything you have mentioned unfortunately but noticed no one had replied so hence wanting to say something. I have had a colonoscopy in the past and was awake. They gave me a slight sedation though I think. Wishing you the very best and sending hope everything comes back clear xx

Firstly I would say yes to sedation I had a colonoscopy a few months ago with sedation and whilst I was wide awake I never felt a thing and it seemed to be over in minutes within half an hour I had left the hospital with my hubby ,secondly I had a positive bowel test and fit test hence the colonoscopy ,they will tell you afterwards what they found that could be causing the blood mine was diverticulitis and a polyp nothing nasty ,its more likely to be something like this than cancer .
