Sounds like you are getting the trial. The top rated SCS is Boston Scientific’s Wave writer (rider?). They will carefully insert the lead(s) into the intrathecal space. Then the lead will get connected to an external battery pack. The goal is to get at least 50% pain reduction. I guess you’ll wear it for a couple of days. Just be careful to not bend very much. No reaching up over your head. You don’t want to move that lead in your back. Make sure you are getting the pain relief you want. Not likely to get 100% relit. I went from about a 7 to about a 2/3.
Wish you well.
