I also find that I need those neck pillows when I'm traveling, or sometimes just when I'm sitting for awhile at home. For sleeping I definitely need sturdy neck support as well -- I've worked out something with a memory foam pillow (that fits under my neck) on top of a regular pillow.

My MO has done scans of my neck a couple of times in the past few years and said there is some arthritis there that he believes is due at least in part to the after-effects of radiation.
