Sometimes, whenever I turn my head, I experience an extreme burning sensation on and in the back of my head, normally close to my ears. I can feel the burning inside of my head around the area, and if you touch the skin where the pain is centered, it also feels hot on top. The pain is so severe that my vision is temporarily impared (blurry and I see white spots, at first) and am rendered incapable of any activity, even talking, until it subsides about a minute later. This will only happen, say, once every few months, for no reason aside from the turning of my head in any direction.
I have lived with this for my entire life and had always considered it normal, until I recently began describing the symptom to my family and a few friends and was met with puzzled reactions. My mother speculated that it could possibly neurological, but have yet to see any sort of specialist regarding the issue.
Though my research online was fruitless, I did discovered a few other people shared my symptom, albeit they never got answers, either. Any idea what could be causing this?
