Not sure this is what you're seeking, but years ago I once had craniosacral therapy done on the back of my neck.
I can say this:
Whereas massage used to hurt me terribly (I have FM and am therefore very sensitive) yet with craniosacral, I felt a relieved sensation.
But that may be because my neck wasn't the most sensitive part of me, or it may be because the therapist was a sensitive woman. It didn't relieve my overall fibromyalgia though.
