Welcome to Healing Well's CP forum. I am glad you found us but sorry to hear of your health issues. You can do a quick search here and find a lot of info on the SCS and the pain pump.
I can understand you being leary of the pump that is very reasonable. Please don't misunderstnad this next statement but just how experienced was the dr doing your trial. Any of these devices require a very experienced dr from start to finish. Neither of these devices will totatlly get rid of your pain either. They are designed to help lower your pain level. Each device comes with their own set of issues to deal with too. Once you have an implant it takes quite a while to get it adjusted to the level you need to lower your pain. Expect to have to take break thru meds too, if a dr says he doesn't offer break meds with these devices, then run from his office as fast as you can. A reputable dr will tell you, you will need oral meds even with the devices. Also, once a device is permanemtly implanted, switching drs is very difficult because others for some reason do not want the liability of taking on a patient that has one. I am not trying to persuade you against doing either, you need to know up front what you are dealing with. I wasn't told this by the dr that put my pump in before having it done.
My pain pump was put in back in June of 05 for lower back pain. My pump only addresses my lower back pain, nothing else. After the first year I decided I had made a mistake because my pain was worse instead of getting better. Little did I know that my dr was way too under educated in pain pumps and the medication that goes in them. A dr needs to understand compounding medication for these pumps, if he doesn't you are screwed. Once he got my pump to a certain amount there were no more increases in the medications, no change out to try a diffferent medication-nothing. I had to realize & accept this was as good as it got. I could not stand up up straight, I was bent over. I had no quality of life. This was not the life he told me to expect after the pump. Then he decided to quit pain mgt and go back into anesthesiology. That was a blessing in disguise for me and 45 other patients of his with pumps. He referred us to a retired neurosurgeon that had over a decade of experience with pumps and handled pump patients only. Not only that she mixes her own compounds for the pumps right there in her office.
I have been with this new dr a year this past January. She was shocked and appalled at the 46 pump patients that got referred to her. Not only were we under medicated in our pumps, as a pain patient we were grossly under treated. Her words not mine. She did make adjustments in the meds in my pump, changed the dose of my BT meds and thanks to this wonderful dr I now have a life. Yes, I still have pain and I always will but I can tolerate what I have. Understand the pump is not a quick fix and neither is the SCS. I am telling you my story so you can hear the down side to what can hapen with these devices if the dr is not knowledgeable. Any rookie can implant one-managing it is a different ballgame. I honestly do not know if the punp is designed for pelvic pain, I have not heard of it being used for that area of the body. I would suggest that you go to Medtronic.com and read up on the pumps and placement of the pumps. I could go on for days about the goodness of a pump but we have to limit the size of our posts, this is why I said to do a search here at the forum and you can find tons of posts on both devices.
