mtbc | Identifying a line of pain

Sometimes I get a sharp pain running in a line from the top of my forehead across the top of my head to the back. Along a short collinear segment^* I also get a brief stabbing pain from the base of my skull down into my neck. Both these occur on the right side of my head. Guessing that these might be colocated with anatomical features I searched for pictures of inside-heads and found that the neck pain seems along my lesser occipital nerve and the other pain seems along the greater one. The greater occipital nerve does not seem to extend far enough forward to explain the path of that top pain but I also read about the excellently named epicrania fugax which can occur along a line commencing and terminating in the distributions of different nerves^† which sounds difficult to explain but nearer the front there is the supraorbital nerve. I feel no sense of my pain moving in the manner described, it occupies the whole line at once, but probably there is some other classification for that; linear headache looked a promising alternative but mine feels epicranial.
