when i move my eyes real fast i get this shocking/intense pain in my head and sometimes to my upper chest, it will only happen when i make sudden eye movement, the pain is intense and only lasts for a sec but it will happen all day, or like before i try to go to sleep the movement of my eyes will make my whole body flinch.kinda like i was being shocked. i didnt know what was causing it at first but ive realized its from the movement of my eyes. did i damage the nerves in my eyes or something. if somebody can shed some light on this for me it would be appreciated...thanks
