I had bad ears before I went into the Navy. I almost did not get in because of it. So the put me on a flight deck. (not kidding) Like H20 I also have tinitus. I dont hunt with hearing protection but always have it when practicing. I shot a friends .357 with out ear plugs...and after one shot my left ear is screwed forever. Since that day I have to use my right ear to use the phone. You might have a wax build-up because of the shooting. (I'm not a doctor and I don't play one on TV) I have been told sometimes that will happen. NOW...I do not know if that is a bunch of crap or not. But it might be something to ask the Doc.
