I had a C1 C2 fusion last October for Os odontoidium. I was doing fine until a week ago. It started with a pulling sensation on the top of my scalp with neck movement. It has escalated to full on pain. When I move my neck out, or down and out, I get a electric shock like feeling on top of my head. If I keep my neck in the same postition I will continue to get the pain. If I retract it it will go away, but leaves the area with a burning sensation. I don't have any other symptoms. Is this related to the surgery, or could it be unrelated?
