I understand that you cannot get a second opinion. Therefor it is necessary to make sure you keep the communication with your doctor open. I address my concerns about the medications, directly to my doctor. He does not mind my questions, and answers thoughtfully. If you keep a pain journal that will help when you talk to him. Pain medications especially if you are on them a long time, need to be monitored on a regular basis. In my case, I will most likely be on them the rest of my life. Of course I am concerned about long term effects. Don't be afraid and think your doctor will wean you off the medications just because you ask questions. I think the opposite would happen, he would respect you more, because you brought up the questions concerning long term use. The doctor wants to give relief, not hurt you. I understand the fear of being weened off the medications too, and the resulting pain issues and withdrawl issues that would bring about. However I still think the best way is to tell your doctor what you are thinking and why you are a bit worried. Trust happens over time, and the way to gain the trust is to speak the truth about all of it. This is just my opinion. I do wish you all the best. ginnie
