How long does oxycotin stay in my system?

With the Micheal Jackson thing that happened with the overdose, if your not perscribe with that type of meds then they just drop you and I’ll have a hard time to find another dr to give me my pain meds. I had some oxy’s that were over a year old and took them till I could see the dr but when I have so much pain that I can’t sit,stand or walk and it hurts to move a muscle. Sometimes I just want to die just to stop my pain. I had a friend who’s daughter went through the same thing and she hung herself. I can’t waist my life to do something like that cause I love my wife and daughter. I just want the pain to stop and I’m too far gone for any surguries. I’m just in so much pain and the insurence companies want to try cheaper and new things that just don’t work. I’m 224#,6’ tall and I hope that it’s just all gone out of my system by thurs or fri when I make another appt. Thanks for the info, I’ll just keep drinking lots of water and take V-12 and hope it’s out by then. Sorry for this being so long but I just need to vent out. Another thing about medicare which pisses me off, they say that I could have a surgury to put a morphine pump in me but won’t pay for the morphine to go in it. How stupid is that shit!
