Like Gramps said, Its not for everyone. Do as much homework as posible. My trial had the leads all shifted and started to buzz my ass and top leg area. So I didnt use it the whole trial week, but went through with it anyway. A total of 9 hours surgery. It didnt do a thing for me. They adjusted the programs 2 different times, but same results. Then I waited 4 months to take it out and wow what a relief it was just not being in there anymore.
This is only one persons experience, and my nerve pain may be different than yours. I have met people at the pain mngmt that liked thiers so It's not like it doesnt have potential to make your life better. Just do as much research about it, and dont forget, if the pre-trial does not make you feel any better than you might think like Gramps and call it off.
At the least you will give yourself an oppertunity to try it, and then give YOURSELF a chance to see if it's something that would benefit YOU..........
