You know I had the same experience with St. Jude. I emailed two different ambassadors and never had a response. When I talked to the rep for my area when considering the trial I told him and he got right on having an ambassador in my area call me.
I'm approaching 6 months in a few weeks. Putting aside healing from surgery the first 4 months were good. I was getting coverage and lowered my pain meds to 1/4 of what i was taking. All of a sudden a few weeks ago we cannot get coverage in lumbar area and I'm getting these nerve stimulations that are very painful in my ribs and sides. Like a "pinching and "lasso" effect. My PM doctor seems to be unconcerned and no giving me any solutions at this point. I'm very discouraged. Back up to same amount of pain med again.
I had a fusion at L4/L5 in 09 like another reader commented and was labeled as failed back surgery after 2 years of seeing every doctor possible and every procedure out there. This was my last effort to get relief. I refused idea of pain pump. At this moment as I'm typing I'd do anything for some relief. My stimulator has been off for a week.
If interested I've journaled my SCS story to help people considering one even though every one will have different experience.
