I'm scheduled for a selective nerve root block as well. I'm skeptical, at best, especially since the other two times I've allowed needles in my back put me in the hospital with spinal headaches; the runaway winner of the most intense pain I've ever experienced. Nothing else even comes close.
Supposedly these root blocks will pinpoint where the worst of my issues are. They are not intended to be a permanent solution, or so I've been told. The neurosurgeon I'm seeing uses them to pinpoint where worst of my troubles are coming from, given the large number of discs affected.
