I just got this pulsating titanitis about 2 months ago. I think for me it seems to be worse at night time, as I'm lying down. I will eventually cuz I'm so tired these last four or five weeks, fall asleep, and then I'll wake up to the heart pulsating sound in one ear or both, and then a turbulent sound of Rush or pressure or something. I'm going to assume because I've been on the internet lol, that it's blood rushing through the veins and I'm lying down so it's coming down that direction. I'm so scared and it's obviously annoying. During the day it's better not 100% but better. Night time I just dread

Look at http://www.whooshers.com for MDs who understand “pulsatile tinnitus.”
I saw 2 neurointerventional radiologists in NYU-Langone 10+years ago.
