A pain specialist is key.
The DEA, drug enforcement agency makes it VERY hard on doctor's who prescribe pain meds.
They look over their records, they question them, they hassle them, and most doctors just don't want that. Then there are the possible addiction issues, and dependence is a given.
Some doctors don't mind dealing with the dea, or helping with addiction problems.
I am not at all saying you are a bad person, or a good person, it makes no difference.
Remember that we are talking about
the MOST powerful medications on the planet here.
Pain med. doctors will take this challenge on.
They have you sign an opiod contract, you will not get narcotics from any other doctor.
Even if you have a colon test, you need to bring a copy of what was given to you to the pain med doctor so they can put it in your file.
They give urine tests, to make certain you are using their meds. Another reason to make certain you stay on top of any other narcotics given to you.
It's not an easy road, but I think it's well worth it.
Also, A pain med doctor can help you if you have any type of addiction issues.
Your Primary doc. or even your g.i. doc is inclined at that point to stop treating you all together.
P.S. There is a pain forum right here on healingwell, which discusses these things in further detail, check right above the Crohns disease link for chronic pain.
