It's likely your respiratory system around your middle ears and sinuses,. etc. I can experience similar pusatile sensations deep in my ears during and after heavy activity in hot weather with allergies acting up. It's worse leaning forward and laying on my side.
The nearby arterial heartbeat pressure sounds may increase if your middle ears have excess fluid pressure that's not draining through your eustachian tubes. You may need to port those sub's with a decongestant after a medical exam ! Squish, squish squish...hope your much better soon.
