I have been hearing and feeling my heartbeat in my ear loudly in the morning lately and when I do my eyes will go in and out with the heart beat. I have left subclavian steel syndrome they put in a stint at the aortic arch and my ribs crushed it so it formed its own bypass. So I was wondering if it was that? But I also have a leaky valve is what my cardiologist said. But I fell and hit my chin and now my jaw is over to my right side but I hear the heartbeat and feel it throb in my left ear. Also my heart has been racing sometimes lately. What do you think is causing this?
