Hello Everyone. I am new to this site. I have had T for years, maybe because I am a musician and sit in front of brass players and percussion, but I have had a really annoying high- pitched sound for the past few months non-stop. After laying down for awhile it goes away, but comes again when I sit up. Is this stress or maybe even a jaw-related issue? I got braces 5 months ago, but only on the front 6 teeth top and bottom. I am 50. I can't get into an ENT until February! Thanks!
