Hi Imnew here, I was due to have decompression and a spacer put between two misaglined vertebrae next week but the surgeon cant now do it. A different surgeon says he cant do it as the vertebrae are beginning to fuse and has offered decompression alone. Both surgeons were using the same scans. It will months before the first surgeon is available again. If I wait for him will the fuse have progressed so it still can't be done even by him? Or does fusing take a long time? I am in a lot of pain. Will the pain stop if it does fuse itself? How long does that take?
