Sorry to bother you, but I read one of your comments about the vibration you feel in your head and how it stops when you shake your head or hum. I've been dealing with the exact same thing for about a month along with distortions so I've been desperate to find someone who has the same problem I have. Did this ever go away for you? Also, does/did yours go away or quieten when you plug your ear/s with an earbud?
