Welcome to NT! You've come upon a WONDERFUL place full of caring people who 'know' what this is all about.......living in this amount of pain is a complete ripoff, and I am so very sorry to hear about the accident that has left you in this condition......
AND you have young twins!! (I too have twin boys age 15)......

Like the others have said, this is a wonderful 'family'....and we talk 'real talk'....not the commercialized stuff you get from searching the websites of these units......
The good news I'm seeing is you've got a Dr who wants to give you a chance at this! If you've got a good relationship with your doctor and he's looking out for your best interest....then DO THE TRIAL!! It could possibly be something that may give you back a decent quality of life!
Several here have their SCS's due to car accidents.
If you have insurance to cover this, then go for it! The trial procedure will give you a chance to weigh your options and you can find out if this is something that may work.
If the trial proves to be of no benefit, then at least you have tried.

I hope you stick around and feel welcome here.....
We all look out for each other and this forum has been a Godsend ....
Even if you don't go with the SCS, the other forums here are full of folks who know what it's like to live with chronic pain.....and we all learn and grow from one another.
I felt completely alone in my battle until I came upon this wonderful place....

It's good to have you.......
Just holler if you need help in finding your way around.....

Truly Caring
Rae
