Almost the exact thing to me, 20+ years of tinnitus which sits calmly in the background most of the time except when I read the word tinnitus, or I'm feeling anxious for some reason: when I can't fall asleep when I need a good rest, life stresses, and those moments when a different pitch shows up in one ear and louder. In those occasions I can clearly hear the tone of mine.

It's mildly annoying but I've definitely learnt to live with it pretty ok.

Haha, its funny you say that because I've been reading a novel at the moment where the main character has debilitating tinnitus, and every time the author describes it, I can hear my own.

Same here! Just reading the title of this post made me aware of mine for the first time all day.
