Do you ever experience that sensation where you feel your heartbeat somewhere that isn't your heart itself? Such as your heartbeat pounding in your head when you have a headache.

I feel it in my upper back, my neck, the back if my head, the rest of my head and all the way to the sides of my face. Its mostly an annoying sensation. Sometimes when I'm trying to sleep it's so strong, it feels like my head is rocking in tune to my heartbeat. It isn't of course. That is (ironically?) All in my head.

It's not terribly painful although it does usually accompany a dull but strong headache that leaves one a but out of breath and dizzy. It usually keeps me from sleeping and/or work a few days a month.

I just wondered if anyone else ever experiences this?
