[|Human|] Occasionally I will get a tightness feeling in the back of my head, in the cerebellum area and then a painful popping sensation afterwards. Generally I ll get a kind of shocking feeling that will start on the top of my head, travel to the back of my head and then throughout my body. This has been going on for years now and I have been to a doctor for it but they didn t think anything was wrong. Is there?
[|AI|]  Hello dear friend, Please accept my concerns for you. You mentioned that it is occasional, that you tend to have such episodes. Please make it clear about a few points-1) what is the frequency of these episodes, ie, once in a week, once in a month or once in a year and likewise.2)How long does each episode last?3)Are there any triggering factors for your episode-may be anything, cheese,coffee, smoke,stress, sunlight,lack of sleep. If you don't know yet, try to watch out if there is anything associated?4)Do you have any abnormality in vision, during these episodes?-like reading half words, seeing star like things, shimmering or flashing lights, light in a zigzag fashion? Closest possibility if any of an organic cause in your case can be of a migraine variant and to rule out the same, i asked you the above questions. If I had been your treating physician, i would have asked you to get a contrast enhanced CT scan done to rule out any structural abnormalities, still. You can discuss the possibilities, accordingly, with a neurologist. I hope it helps you.
