I have a sound like a soda can full of BB's shaking in my ear in response to noise. When there is complete silence, I have no ear noise. As soon as there is a slight sound, the soda can starts shaking those BB's. This is opposite of the usual tinnitus and I was wondering if anyone else has this and did it go away and of so, how did you do it? Thank you for any help - I have had it for 5 years and it's getting me very down by now.
