I'm confused about the UK health system. Since you have government health care, as we do here in Canada, I was surprised to read that you would have to pay to see a specialist. I know all our systems are different but I just assumed that you would be able to be referred to a specialist by your GP and not have to pay to see him/her or pay to have a test like a colonoscopy done. Would you be able to get a colonoscopy ordered by your GP? Mine is sending me for one - yuck!
