I used to have severe problems in both ears, but it has gone much more mild. Not only tinnitus in form of high pitched "sin-tone" type of whistle, but also issues with pressure, additional humming, clicks and snaps and such. Over sensitivity to sound. Not even loud sounds, but sounds in general. Any sudden sound could result "shock reaction", being as small as assembling jewel boxes.
However, during few years and being careful with loud situations, it got better and it's no longer disturbingly strong.
Few things what I have learned and read about tinnitus, is that for some people, it is also very much physical issue. Even as simple as neck-muscle tension. If tinnitus is simply the one specific frequency ringing in your ears, I believe there has been successful ways of helping it with adding graphic EQ to stereo system, muting the ringing frequency totally and playing music through-out the night. Theory of some of tinnitus being more of brain related trauma has been proven by this. Brain slowly adjusts traumatized frequency may heal. More simple physical side may be even more clear. Delicate ears damaged merely be sitting hours and hours at shitty deck job. Even with zero noise involved.
