I get this every time I swallow. Louder in my right ear than my left. I used to suffer from mild lockjaw as a teen, but that eventually subsided. I was told at the time by my GP that my jaw slightly dislocates on the right hand side... I think this must be the cause of my T. I was told to see a dentist... when I told the dentist about it, I was told to go back to my GP! I also have a whooshing noise in both ears. Not sure if this is related to the same thing or not.
