Upper left abdomen pain

[Jellylupo]

I've had my Spleen revomed 19 years ago and for the past year or so I keep having pain in that area. I had a two CAT scans and my family Doctor keeps telling me that there is nothing wrong but I keep having pain. I don't know what to do next. Can some one direct me in the right direction?
Thank you.

The pain could last from ten minutes an hour. it depends what I am doing. It doesn't wake me up but it does start to hurt when I'm sitting. the only thing that helps is that I have to sit up straight and lean to my right. I don't think that anything has changed with my bowel habits but I have never been consistent.

Hi,
How long does each episode of pain last?
Any relieving or worsening factors?
Any change in bowel habits?
Does the pain wake you up from sleep?
