Hi there. Try the chronic pain forum and the SCS forum. This one isn't often used I've noticed. There is a man called Mark56 who has had cervical surgery, quite a lot after a horrific life changing accident. Maybe see if you can get some advice from him.

I'm sorry I can't offer much help, I've got c5/6 damage after a head on MVA but most of the pain I suffer is in the lumbar region from a horse riding accident as a teenager. Since my MVA I've had a number of rhyzotomies on my neck and also lumbar region. More recently I've had another lumbar fusion and will have another to L3 this year. Anyway. I'm wondering if you have considered rhyzotomies to your neck?
