My father had knee replacement surgery on June 14th. He has been on 7.5 since then. He also quit smoking that same day and is on a step down patch. He is getting around very well, all the therapist have praised his recovery. I'm constantly hearing him say how he can't sleep or how his bowles are not good, how he is depressed, etc.. he says the "pain" is hardly there, yet he still usually takes a pain pill 1-2 times a day. How can I tell if he is getting addicted? He is good at telling me one thing and the doctor/nurses another and I found out he now also has sleeping pills and another 90 more percocet. HELP!! Am I being overly concerned when the doctor tells me father to take the pills for as long as he feels he needs them??
