Ugh...sorry to hear that. I've never had a migraine, but I understand they're debilitating.

I wonder...if your blood pressure is low, if it has been like that for awhile, if the increase caused by orgasm, even if it returns it to a normal BP or even below normal, if that, due to your body being used to low blood pressure, would cause the same effect that it would to a person with normal blood pressure? lol Again, not my specialty, but that would make sense (on paper, at least ).
