Hi, I am experiencing sporadic pain in my head. The pain is like a zing, it moves from bottom right back side of head to upper middle back side of head. It s sorta pulsing like. It does not occur on any schedule, just shows up. This has been going on for at least 6 months. In the past week I have also started to experience tingling like numbness on the right lower side of my face from ear to chin. I have had an x-ray and cat scan. They can t find anything. They say they will refer me to neuro-surgeon. 4-5 years ago I had stenosis of neck, c3-c7, operated on. Is this more stenosis?
