I think that would depend on what is in the pain pump.
I had a temp pain pump after some surgery a few years ago but it only supplied a local anestic to the surgery area to numb it. I had to take orals if the pain got worse.
If the pain pump is supplying opiates - then I wouldn't think so.
Hope that helps, but it definitely sounds like a question for the Dr. and/or detox center.
