I also suffer from the constant ringing. Go see the doc if you want it will go away but you've done some damage. I have shot my whole life skeet, trap, spoting clays you name it I always wore ear protection. I have also hunted all of my life and never wore protection! My Doc. told me anytime you get your ears "rung" you've done permanent damage. Whether it be from a loud concert or running a jackhammer all day. Typically most right handed shooters have left ear damage, because that is the ear that is exposed to the muzzle and visa,versa for left handed shooters. I'm just about deaf in my left ear. Of course my wife just says I'm deaf.
