Lost - you said that the pain was not localized. Does that mean it is all over your head, or is it like a band of pain? What sensation do you get, ie]sharp dagger like pain, ponding headache (like with your heartbeat), dull annoying ache...? Does your neck and shoulders get tense before a headache? Do you feel a little spacy before a headache, or durring for that matter? (when I say spacy - I mean a little out of your self, kindof like bored, not really 'into' whatever you are doing). Do your temples hurt more than the rest of your head? Does it hurt between your ears and your jaw? Does the top of your spine (Where it meets with the base of your skull) hurt more than the rest? Does it hurt behind your eyes? Is their pain at the top of your head? Can you feel anything else on your body that is tight or sore?
Just a few questions...
