C.O.
I would try a hot and moist heating pad. While it doesn't hurt right now, you could end up stiffening your neck by lack of movement. So the moist heating pad will loosen your neck muscles to allow for movement.
I would ask Rob, when he gets home, to GENTLY pull my head/neck while his feet are on my shoulders (yes, do this lying down!!) :) and see if that resets the vertebrae that sounds like it's "off"..
