I had a spinal fusion in sept 2011 almost 9 mos. ago. I live with daily pain in my lower back. I was fused from L4 to S1. I also have a feeling above where fusion is of my back popping out of alignment to popping back in. It doesn't cause pain when this happens. I can do something as simple as moving my leg and it will happen. I did tell the neurosurgeon that this was happening didn't say a word just wrote it in the chart. I want to know if this is a normal and to live with daily pain. I have been in therapy for 3 mos and only thing that it is really helping is my balance.
