You know, it is possible that you were partially obstructed, but it didn't show on the CT. No test is 100%. I've had that happen where my symptoms mimicked prior symptoms of an obstruction, but tests don't show it. My GI usually treats me based on symptoms, and usually things "pass" within a few days.
Darvocet doesn't stop me up, but other pain meds do. For me codeine is the worst :( Can you ask your doc to prescribe something else for pain? Maybe another type of pain med won't slow things down.
I hope you're starting to feel better. Hopefully as you get less full you'll feel better!
