Hi Julie,
I can't speak from experience here but I hope you get good relief.
I would certainly advocate doing your research on what your doc has available. There are a lot of options on how the battery is charged, whether is it wireless, higher frequency, etc. Some of those details can make a big difference in how much it helps and in how convenient it is.
There is an SCS subforum under the Medications and Treatments page where you can find a lot of info.
Let us know when you go ahead so we can send positive thoughts and healing love your way.
