Yes, I have a pump now and it is filled with Fentanyl along with Bupivacain Bupivacain is mainly used as a nerve blocking agent or used in anesthesia. I have had a pump for over 10yrs (battery replaced twice) and I believe that 'my' pump is useless and maybe, like you, I am in agony most of my nights and days... MY lead tubes are on the outside of my spine due to myself having 16 screws that may block the physician from placing them in the correct alignment , which should be on the 'Inside' of the spinal canal. I, myself would much rather take oral medication than have a pump. This response is only because I will have the knowledge of 'what', 'how much' and 'when' my medicine is taken. I believe that a pain pump is absolutely USELESS! BUT, this is what my insurance is willing to pay for. My Doctor told me that he may be in process of a complete stop of pump medication, ONLY, because, "There is no money in it"... What a sad statement. If you're hurting, you know your body... Can you go back to oral medication, where, by knowledge, you have some control?
Good Luck to you and hang in there!! Knowledge is the power to your satisfaction of you feeling better. Ralff P.
