I hope you've had a good weekend goose, and if you like, I'll hold your hand. I too, have just been referred under the 2 week rule for a CT scan to look at the pancreas (is that what you are being referred for?)
In my case, I'm not too alarmed - I've had digestive problems for quite a while, and eventually decided to go to the GP to see if we can get to the bottom of the cause. I've had blood/stool/ultrasound tests, which have all come back negative, so after a discussion with my GP yesterday, she felt the CT scan was the next step to RULE OUT the possibility of C. It's just a tick-box thing - over 60, abdominal problems, these are criteria that trigger further investigations. Although I have to say, I don't have any other symptoms that would worry me (I know you say you do) so I am not allowing myself to be alarmed - yet! The GP has also referred me for a non-urgent gastroscopy, which I'm not exactly delighted about, as I'll have to have it without sedation due to living alone and not having someone to accompany me. However, I shall just have to put on me big girls' pants and get on with it!
So please accept my best wishes for a successful outcome (for both of us!)
