Hello,
When it rains, it pours. I'm 40, F, in good health, and this week, out of the blue, I have two severe headaches that are blindingly painful with extreme light sensitivity. Light is blurring my vision. No history of headaches other than tension headaches which are about 1/10th as painful as these, and they are truly infrequent. One came on after taking a very short (1/2 mile) hike. Both have put me in a dark room, wincing in pain, for days. The pain is just exploding.
