I'm not sure what started my tinnitus ... it sort of crept up on me over the last few years. Doc says nothing can be done for it. It is worse when I am tired (evenings) and it is centred in the middle of my head. It is really bad at the moment as it is the end of a very hectic week at work. I do find having TV or radio on in the background helps divert my attention from it a lot of the time ... but whilst my husband has it sometimes he doesn't understand about the TV as he finds it annoying. Hope it quietens down a bit for you.
