In March 2013, I had an X-LIF spine fusion done to my low back. The Dr told menus was an 85% success rate surgery.....My back hurts just as bad or worse than before the surgery. Had anyone else had the procedure done in there low back? Since surgery, much more numbness and severe pain. Recent MRI and CT scan show no hardware damage, new dr stated just a failed surgery. ..has anyone else experienced similar problems? They are talking about possibly another surgery and installation of a electronic back stimulator thats implanted....Back problems sure do suck......
