Since january of this year i have had a colonoscopy upper endoscopy abd us's several abd/pel ct scans hida scan n negative, why do i still have pain?

Ask your doc!: Most appropriate for the doctors that have ordered all these tests to discuss the results with you, and give you a clue as to what they have found or not found (sometimes even more important!). Any other answer is a guess on anyone's part--if all the tests really are 'normal' you should be reassured that nothing horrible hads been found thus far!

Where is the pain: More information is needed to answer your question. Location of pain, severity, what makes the pain worse or better, associated with foods or drinks etc.
