Can you describe what the pain feels like?
Firstly, it is one-sided. > 95% of the time for me it is left hand side. Imagine a clamp around your head tightening, but at the same time there is a sharp hot object behind your left eye trying to drill an exit hole through your eye. The clamp continues to tighten – and every time that you bargain with the universe that “OK, thats my limit, stop now pleas” it tightens a little more. You vomit, loss of balance, and sometimes get quite scared for no real reason. You know what is going on (most of the time) but you have a deep feeling of fear. I also taste stone at the top of my head (how weird).
