I know very little about pain pumps. BUT, I personally would feel more comfortable with a doctor I can work with. It bothers me that he pretty much is telling you he knows better than you when it comes to how you feel. I am sure he knows his stuff....it just seems off putting. I agree that a call to Medtronics for their opinion would be a good starting point. I also agree that YOU know best about what you feel should happen. I hope you get a solution quickly!
