I saw the dr this morning.
He didn't really know what was wrong, and admitted he was baffled, he actually said that. My pulse and blood pressure were high and that led him to think the headaches might be from high blood pressure, but since I've had exactly the same happen several times when visiting a dr or a hospital (heart rate 140 bpm) I wasn't too worried. Besides, I was asked yesterday or day before to measure my heart rate when I was calm at home, and it was only 68 then. And my headache isn't throbbing at all and I think it is when due to high blood pressure.
So... he concluded it might be due to a viral infection, and prescribed anti-biotics. However I'd forgotten until it was pointed out to me that anti-biotics are of no use against viral infections...

. He said to come back in two weeks if I still have the headache then, and then blood tests would be done.
He really did ask me a lot of questions, including trying to go all psychological, asking me how I felt about my friend's bf, and how I feel not having a bf *sigh*. lolol. But he never looked into my eyes though, and I've read that all people presenting with a new kind of headache ought to have their eyes looked at. i couldn't think of any way of tactfully suggesting it so I said nothing. Perhaps it will happen next time if I still have the headache. He did say it isn't a migraine though.
