Madge, if you had an MRA back in '05, that's really not too long ago, but of course it probably wouldn't hurt to have a followup in light of your symptoms. However, the 'rush' you describe and the shakiness sound like a wee panic episode.
Still, if you have a blood pressure monitor, you might want to check your BP at the time you feel this 'pounding' sensation. It could be a brief bout of high blood pressure, and that would be worth investigating.
I experience the pulsing in my ear too, but only occasionally. I don't know what causes it though.
When we get to around 60, it's always a good idea to have those carotid arteries in the neck checked out. Usually, a person's regular doctor does this by just putting a stethoscope against the neck to listen for unusual noises (called bruits) in the vessels, but there are a couple more in-depth scans like MRA and Doppler that are quick and easy. You might ask your doc for one.
Jannie, do you feel the pulsing elsewhere in your body?
Yarrow, thanks very much. I did have an MRI with MRA back 2005 (when I was 62) and the carotids were okay. But a lot of time has passed since then. I appreciate your comment.
Another thing I just thought of. When I get the pounding heartbeat, I often get what feels like an adrenalin rush, as though I'd had a bad dream and just woke up. Feel kind of shaky inside sometimes.
I did check my BP when I was feeling this pounding sensation, and it was the same as usual 116/ 68. Pulse was 72. Seems all right.
But I think I'll ask to have my carotids checked when I go in for my annual physical in a few months.
