I agree with Christine, its the pills themselves. There have been alot of new rules and regulations put on these pain pills, making it very difficult for those on long term pain management. Its not fair, but sadly to many people abused the system for these drugs and everyone who actually needs them has to pay the price. I do not feel they should be changing your perscription without discussing it with you first though, so as Christine said I would recommend getting in with a pain specialist. I am sorry you are having so much trouble and understand your frustration. I wish you luck.
