I just went thru headache scares! I had strange headaches across my forehead and over the top of my head, especially when standing up. It lasted 2 weeks and the last two days have been pretty good. My Dr, an eye Dr and an er Dr both said its between sinuses and tension. Well of course being an ha, I made an appt with a neurologist for this Monday lol. But my symptoms have gotten better, not worse so I'm a little reassured.
the worsening of headaches when standing up is fairly normal, your blood pressure flucuates thru out the day especially with activity. Hope you feel better!
