I'm not surprised Percocet is no longer working as it is a short-acting oxycodone with acetaminophen, not meant to be used long-term for chronic pain.  You would need an extended release medication for round-the-clock pain treatment. I'm also not surprised that 80 mg of OxyContin brought such good pain relief since that is the highest oral dosage made. I seriously doubt that most doctors would prescribe that dosage for long-term use. (The PDR recommends starting patients on 10 mg.)   As you look for a doctor to help you with pain relief, I feel I need to caution you about a few things.  Doctors are usually very hesitant to prescribe opioid medications like OcyContin on a long-term basis.  Because these drugs are so often abused, the DEA monitors them closely.  Physicians who prescribe them too freely or who prescribe them to people who turn out to be selling them are often prosecuted. Therefore, most doctors are cautious about prescribing them and are always on the lookout for potential abuse.  For that reason, I wouldn't recommend telling a doctor that you took your father's 80 mg OcyContin.  Taking someone else's prescription medication is illegal and they may tag you as someone who cannot be trusted to take the medication as prescribed.  And, contrary to the previous answerer's advice, making a scene in the emergency room will most likely get you labeled as a drug seeker.  Once you have that label, no reputable doctor will prescribe opioids for you.    One other thing you didn't mention but I'd like to warn you about just in case – do not ever cut an OxyContin tablet in half for any reason.  Because they are extended release medications, this could result in an unintended overdose, which could be fatal.    As for finding a doctor who takes Medicaid, try contacting your local Medicaid office to see if they have a list of area physicians who accept Medicaid.  If they don't, the only other thing I know is to sit down with the phonebook, start calling all of the local doctors and ask. I wish I had a simpler answer for you on this.    I wish you the best in your search for a doctor and the appropriate medication.  Karen
