I have had lower abdomen pain for about four months that has steadily gotten worse and wakes me up every morning now. It doesn't seem to matter what I eat or don't eat and within the last three weeks pain is now up my right side, and I have some nausea. Passing gas has increased and is more foul in odor, but no change in stools. I had a cat scan with contrast dye and it shows an enlarged bile duct. I am now scheduled for an ultrasound in three days to look further at things. I have been researching online and since I don't have itching or jaundice, I am wondering if anyone knows what could be going on with me? Thanks!
