I guess I will answer my own question.....
I've had GI pain for 25 years. Ulcerative Colitis, Surgery, and now Crohn's. Finally, a couple of years ago I decided to do something about pain since it was driving me nuts.
Since posting this I have tried OxyContin after using Norco for a couple of years. OxyContin works really well for GI distress; slows the gut, kills pain and cramps, and generally restored my function.
Only problem with OxyContin was anxiety, it was high so I switched to Opana ER
which is a powerful Opiate that lasts a solid 8-10 hours. It is a pretty amazing medication.
For Crohn's and UC sufferers, try to stay away from Short-Acting Narcotics like Vicodin, Percocet, and Norco. You will end up chasing the relief, counting pills, and becoming mental about it.
Best to use a Long-Acting (LA) med, and have a supply of Short-Acting meds for (BT) breakthrough pain. This approach is a fairly standard practice in the pain management world.
Bottom line: Pain meds have been a good addition to my other GI meds. Currently I'm taking Prednsione, EntoCort, Xifaxan, Cipro, Lomotil, Hyoscyamine and Cortisone Enemas.
