Hi Shawley,
I know you from the back board. I just wanted to welcome you here and let you know while I dont know anything about the stim, I do know there are people who post here who either still have one or have had one in the past. I'm sure someone will be along shortly to help you out.
Only a week to go, wow, are you nervous? Do they put you under to put those in, or just use a local?
Hope it helps, I know you have been through a lot with WC and doctors, I hope this is the one thats going to work for you, I know how bad it can be when you have no consistant quality of life.
Best Wishes,
Fabby
