If this is where your problem is, several things may help. Since the pain
is eased by laying down, I think you are just not moving the neck
enough. Try some exercises that will relax the neck and back. don't hold the head in the same position too long. Sewing, knitting, watching tv or computer, reading, etc. are activities that you do without moving the neck around too much. Take breaks and roll the neck and relax the shoulders.
