I have not even done the stim trial yet. My cardiologist says you can't implant one with a pacemaker, which I need to have done. I am concerned about even doing the trial, and feel like my doc is rushing it. I just don't like the idea of electricity from another source running in my spine. He won't even do a pump trial unless I do the SCS trial first. I am even more concerned after reading so many posts where people had complications after it was inserted. I would really rather try the pump because I know what has worked (I've been dealing with this for 11 years now. I had better care in 3 other states, but have nothing but problems since I moved back home. Does anyone have any thoughts on this?
