Your ins won't cover anything related to this, or just the surgery??
Can you appeal that or find a work around, I think most hospitals have a patient representative or someone that helps with things like this??
Some members in the past have contacted their senator or representative about non /ins issues.
Maybe a pain pump or SCS?? Those are spendy too, and ins usually requires an approval process.

What kind of surgery was the dr suggesting?
