Headache at orgasm?

Lately, I've been getting headaches right as I reach orgasm that don't go away for at least five minutes. They're not just a little bit o' pressure in the temple or an average headache, they're the most painful headaches I've ever had, hurting mainly in the front of my head with a concentrated force of what feels like a sledgehammer. It's happened every time without fail. I find that writhing about frantically whilst holding my head seems to make me FEEL like I feel better, but it really doesn't help, and neither do headache medicines, no matter when taken. Is this normal? ; A ; What can I do to stop this? . _ . Help would be very much appreciated.

I've heard of this phenomenon, it's not exactly common, but it is a known thing.  (In other words, a doctor wouldn't look at you and say "that's the oddest thing I've ever heard.")  If you google "headache with orgasm" you'll probably find it.

I think it's called 'coital cephalgia.'
