Oh I know, I was talking about colonoscopy in response to what Cassie had queried. I have no idea about gastroscopy as haven't had one but have unfortunately had two colomoscopies and I wouldn't have that done awake either, not after I was told my descending colon is much curvier than usual and it'd be too painful awake. Yes I guess some people tolerate them okay with a bit of gas and air.
Ive had both with sedation. I wouldnt have any of those without as Im nervous. I wouldnt have a hysteroscopy again unless I was under general anaesthetic and, I would decide with them whether it was necessary at all, given that I had no symptoms and my gynaecologist was almost sure there was nothing sinister going on inside me before she began that procedure.
