Loooong strory. I have a disease that fused my spine. I fell and broke it. Did 3 months in the Hospital, went home, left alone, fell again. It doesn't take much to snap a fused spine. It's not fused from surgery. It fused in a painful Arthritic process that took years and is still going on. I have a Remicade infusion every couple months to keep it at bay.
