For over 12 years I had so many injections (epidurals, nerve blocks, rhysotomys, steroid -oral and injected with not good results) before I found a doctor that Fused my back. He actually saved my life. So as you can see my L4 L5 and SI are fused. Recently I blew out the L3 L4. The doc tried me on oral steroids and for one day I felt pretty good. The next day it went down hill. Yesterday they did a nerve block injection. How long can I realistically expect that to alleviate pain. Today I feel pretty good. My doc had said steroids, injection then fusion. I am just wondering how long this prolongs the inevitable?
