So this happens often in my right ear, I dont believe its ever happened in the left. Usually it happens while Im at work (hair styling). Today it happened when i was listening to music and it was like I could turn the thumping off and on. Basically I was laying down on a pillow on my right ear. I started playing music on my phone that had a beat and the thumping began at the pace of the beat and as the beat quickened so did the thumping. When I turned the music off my ear stopped thumping as well. I tested to see if the left ear does it, but it doesn't. Does anyone know what this is and if it's anything to be concerned about?
