I have an intermittent low hum in my right ear only. It sometimes goes ‘on and off’ when I turn my head from side to side. It also sometimes starts if I press around my earlobe area. Sometimes it is in synch with my heartbeat and other times it is just a continuous hum. I have had my ear checked and my wax is normal levels and there is no damage to my eardrum. I am 49 yr old male.
