The best pillow that I have seen for neck and shoulder pain relief is by far the arc4life traction neck pillow. It comes in small, medium and large and the sizing is important for your head and neck.
Yes, this pillow can take some time to get used to for some patients, but overall it provides tremendous relief. What makes it so great is that it has contours on it that allow the natural c curve in your neck to be in the right position for side sleeping and for back sleeping. This pillow gives optimal neck support and gentle neck stretching when used correctly.
