noob with an rs

haha im serious, man, cuz i am in one ear. When i was 18, I went to the desert with a couple of buddies to shoot some handguns. well, we weren't very prepared with gear and my buddy shot a nine millimeter pistol right next to my ear.. like i was kneeling down by a fence and my buddy let a couple off. it didn't bother me.. until i realized i hadn't gained some of the hearing back in my left ear. basically, my left ear has a much harder time picking up the higher frequencies. im wondering if you've lost any of your hearing.. i wouldn't be surprised if u did. ;D
