honestly, I feel absolutely terrible for him, because I can't even imagine how painful the procedures will be, and they aren't going to be able to give him shit for it. he's too much of a liability to give anything thats as strong as needed, and whatever he does get he probably has a sky high tolerance for.
While in the hospital, they will treat him regardless of his addiction past. They will even account for his tolerance in their dosing of his pain medications. As for take home meds, that is where he is out of luck. Though, I'm sure he will be provided with strong non-narcotic pain meds such as Toradol.
