Constant high pitch squeal in my ears 24/7 since I can't remember when (really long time). Around planes since 1973 flying and fixing, add to that shooting sports since I was a kid......................................gets aggravating at times. Can't stand loud resonating places as some restaurants can be nor loud music. Some noises make my ears feel like they are being poked with an ice pick. Also have hearing loss in both ears, left being worse. ENT looked and said nothing could be done, so I deal with it.
