I am soooooooo like you with checking out symptoms online, Cathi. For the most part, we have the NHS Direct here which allows us to do just that and if uncertain, can call in to speak to a nurse on duty who would give further advise.

I had colonoscopy in the recent past and honestly, I found the procedure more embarassing than alarming. I pray all goes well with yours. And, I understand very well one's concern in view of genetics. But, in a way, it helps because you know what symptoms to look out for and when one suspects that a pattern is there, one can seek early treatment for it. The part of the legacy of the generation before us is that we can learn from their experience. I pray and hope all turns out well.
