Heart beating in my ear.

I've been feeling this light throbbing sensation and hearing this whirring, wooshing sound in my right ear since about last Thursday or Friday.

At first I feared that a bug might've gotten in there while I was sleeping (I had a similar scare a few months back when weird things were going on in my left ear). Turns out that the sound in my right ear isn't a bug, but my pulse. I've been hearing/feeling my heart beating in my ear this whole time. A couple days back I was randomly compelled to take my pulse, and as soon as I applied the requisite pressure to my neck just under my right jaw, the throbbingwhirringwooshing stopped as if muted. Took my fingers off the spot and the throbbingwhirringwooshing kept going like before.

Haven't experienced this before, and I'm not a doctor, so I don't know what this means. I tried googling it (not always the best idea when something's going wonky with your body), and plausible answers ranged from nothing-to-worry-about to the onset of hearing loss. I certainly hope it's not the latter. Maybe I'll go get this thing checked out. Dunno. In the meantime, though, I'm rather fascinated. I mean come on, I can hear my own hearbeat! Got new access to my pulse and don't even have to lift a finger.
