I know this may be a long shot, but I am having the same exact problem! I have had this before but they would never last. I get the stabbing, electric like, zapping, on the right side of my head, in the back, a bit higher that the top of my ear. And I am noticing now that my ear feels like a mild earache, but not always. I read up on Occipital Neuralgia and that would make sense, as I have had serious head injuries in a car collision years ago. I also have neck arthritis. But, do we just live with this? Have you found relief?
