I was first affected by Tinnitus in 2012 after a bout of Labyrinthitis in my left ear. The noise in one ear was annoying and at it’s worst an incredible distraction. Watching TV or even listening to music was very hard. My GP advised that it was normal after this kind of infection and that it should pass. There was no mention of when!
I don’t have any formal medical training. This is not a medical book and the solution is not medical: it is however one that works.
