I was wondering if anyone who has had experiences with loose screws or hardware could tell me what kind of symptoms they had. At the very top of my fusion, there is one small and extremely tender spot on the left side of my spine that coincides with a screw. It hurts very much to the touch and begins to hurt sharply after sitting unsupported for only a few minutes. I also have a very tingly feeling coming right from that one spot. Because of the way it is isolated to only that very tiny area, I am thinking maybe there is something wrong with the screw? Any ideas? Thanks!
