I had back fusion Surgery in Sept 2014. 3 months later I was still experiencing pain and went to see a different Dr to get a second opinion and find out what the reason could be why I am still experiencing pain. He said that the pain could come from inflammation in the facet joints in the level above the fusion. He gave me facet joint injections but struggled to inject me on the left side of my back. He said it was because of fibrosis and continued anyway. In the days following the injections I struggled to control my bladder and started experiencing pain on my left side where I've never experienced pain before (I always only used to experience pain on my right side). Could it be possible that when he injected me into the sack that surrounds the facet joint, that it ruptured? And now the fluid inside the sack is leaking out and causing even worse inflammation and pain in an area which I didn't have pain before?
