I have a SCS and the trial actually worked less than the permanant. For me, I have huge family support and my doctor actually changes out medicines seasonally. For instance more in winter than summer or visa versa. My SCS covers abou 40-50 percent of pain. Which is HUGE when you look at the full scale of 100%. It is a HUGE lifestyle change as I am young and was once an athlete. I have mine in my neck which is harder because it goes all the way down your back instead of just the lumbar spine. Everything worked out wonderfully and I decided to put it in. I never considered a pain pump, as my PM doctor told me the SCS was a option over more medications. I have had mine in for only 3 months, but those 3 months have been great over the incision sx pain from the implant.
