I have ibs with bowel movements and severe lower abdominal pain. it's managed. i now have severe pain in the upper abdomen only. all tests negative. ?

What tests?: Hard to say without knowing what those tests you had done are. Would re-post with more details.

2 many possibilities: very complex symptom with many possible causes. a thorough history and exam is your best likelihood of getting your answer. I would recommend continuing to work with your health care provider on finding the answer. wish you the best.
