I had a successful SCS trial just back in February. I haven't read all the discussions between you and FatherJohn, but I can tell you that because my pain is located in my right arm the leads had to be put up into my neck near C2. With needing leads implanted that far up in the cervical space there is a whole bunch of issues that I can discuss at length if you're interested.
My PM doctor, who did my trial, did not require me to cease taking my meds. He merely requested that I go without as often as possible knowing how horrid my pain is on a day to day basis.
I had a Bostcom Scientific PP model installed and my rep was fantastic and very supportive; I heard from her every day, and the one time I needed a readjustment for better coverage she was out the next day to do it.
There are some minor nuances that come with the trial; tape and padding on your back at the insertion site. No baths or showers! If you have long hair, have someone help you wash it in the sink.
Because you ahve to be awake for the insertion they kept me lightly sedated, but I was in discomfort for the rest of the day, mainly my neck because of having the wires shoved up into that region.
As many horror stories as I've heard about Medtronics I have a neighbor across the street who has had her Medtronics unit for a couple years now, and she loves it! It doesn't give her any problems and has actually restored a good portion of her life back to her.
For me the SCS implant is really the only option to help manage my increaseing/spreading pain, but that's the nature of the beast I deal with.
Any questions, ask, and I'll do my best to get back to them. Tonight I need to keep this short as I'm tired and my hand is to swollen and painful to keep typing.
Where, physically, is the pain your doctor is trying to mask with the SCS?
