Hi sorry to hear your have a bad tme of it but know just how feel. Really hope the nerve block injection works for you. I had to have them done in between ops on my back There rite you will need somone with you because it does smart a bit. I know when i had mine done i could watch on the moniter as the needel goes in and moves round till they hit the rite spot and trust everyone in the local area will no to. I dont want to worry you and you will probs been told all about it but it is worth and they do work and help ease the pain. With 3 prolapsed disks and 2 broken vertabra i have a pretty good understanding of pain. I really hope it all works out for you and you get sorted all the best
