I think I experience a similar sensation to what you have experienced. The way I would describe it is as if someone is squeezing part of my brain with a slight tingling sensation running across the surface of my brain. It mainly affects the left side of my head, although recently I have noticed in the right side. I experience this from time to time, and maybe several times a day. I must admit that although I see a headache specialist I have never mentioned this to him, maybe I should!!
