I have heard my heartbeat in my ears for several years now, but my left ear is particularly annoying at times. If I bend my head and put pressure under my ear, the noise lessens in that ear. Also when I bend over, I will get a whooshing sound in my left ear now, almost like when there is water in your ear. There is no pain, but I DID have a lot of wax in that ear and some loss of hearing, until recently, when a doctor removed it. She said that ear had a rather convoluted passage. Do you have any idea what is causing the noises?
