I also have a large lump directly on top of my cervical spine, in the 6th & 7th cervical vertebrae area. It's large, smooth/rounded, and slides vertically (up and down) when I press on it, but not horizontally (from left to right). Mine is also not easy to spot with the naked eye, and when I tilt my head down I can't feel it with my fingers, but when I tilt my head back, it kind of pops out and is easily felt. It's about the size of a marble. And of course now that I know it's there, I can't keep my fingers off of it. I had some xrays done last week, which didn't show much besides what I already knew-there's some kind of mass present. I'm going for an MRI on Friday, and I'm scared to death of what they'll find. I'm a terrible hypochondriac, but hey, even a hypochondriac can be right once in a while. I'm praying it's something benign. I'll try to remember to come back to this forum & post the results. Best of luck to everyone else on here as well. -Angela M.
