I'm not sure what type of nerve block they discussed.
I did 4 rounds of trigger point injections and supposedly nerve blocks that did nothing for me. I was told that more than likely the reason nothing happened was that my problem was no longer just the spinal area, but also scar tissue from my back surgery.
Depending on the level of your pain, I would say that anything was worth a try. Which is what put me through 4 rounds of shots. The HOPE that my pain might be easier. :)
