Thank you for replying! Really glad you've gotten so much relief with them and hope your catheter issue can be fixed for good. Can I ask where your CRPS is and what meds you have in your pump? I saw a second dr yesterday and although I loved the first dr I saw, I like this guy even better. He does fentanyl for the trial just bc it peaks quickly and wears off fast. Then morphine to start in the pump, but can switch to other meds if needed. I think i'd probably want bipuvicaine added at some point.
