I had bad tinnitus after surgery if I lean too far or sideway it sound like super loud ROAR lol it went away in 4 weeks (on activation day) after that no ringing at all, pure silence....
Only time it will start back ringing is when I'm upset and crying it will ring really loud ROAR until I calmed down it stop. And I'm 1 year 6 months post CI.
Don't worry it will go away on your activation day
And you will still have tinnitus when you're upset/crying for rest of your life so its good excuse NOT to get upset, stay happy!
