Well had my first ever Colonoscopy yesterday after requesting one from my GP, not sure if I was lucky but my consultant was brilliant never felt a thing during the procedure but afterwards the stomach cramps doubled me up but considering the examination not a big deal - so if you are due to have one soon then please try and not worry - I think everyone should have one when they get to a certain age. It may save life's and the NHS a small fortune in treating people with bowel problems that could have been treated sooner.
Three biopsies were taken so I get those results back soon but the consultant did state that all looked A1 - but its like you people have said in these forums, it was more for a peace of mind for me than anything else and I think you are right.
Anyway have a good weekend and I hope my short message helps someone.
