Two months ago I had the flu, blew my nose too hard and since then have had a pulsing vibration in my right ear. Went to an ENT no tumors or closed down arteries so now I'll start changing medications and see if this helps. I'm listening at lower levels now, down from 75-85db to 60-75db. Inserting a foam ear plug when not listening to music helps to reduce the intensity of the vibration and sometimes seems to eliminates it!! The vibration is similar to the pulse of the bass in a loud car audio system thumping it's way down the street!!! So one of the things I dislike the most is now something I feel/hear pulsing constantly, life's strange.
