Hi Angie,
I've had revision surgery for the Medtronic SCS in my lower back. Unfortunately for various reasons it didn't work properly for me, and with that my Consultant suggested removing it altogether for a newer SCS. There have been many great reports with this SCS and although I know very little about the St. Jude's some folks on here have one and hopefully they will chip in.
Have you a time frame for this?
I do hope you're pain is managble since,
God bless,
Sinéad
