I am sorry to hear your report. I am not an expert, just know a little. I would be worried a bit too and seek another doctor. This kind of thing where you have problems so quick after the first fusions does seem unusual. You need to get better answers from your neruosurgeon, about this test, and then maybe seek another opinion with your latest test. Stay strong. Sometimes people do have second fusions, and turn out just fine. I am one. ginnie
