@geg1992 I do have to say that I think personality has some kind of connection to all this; the people I know who have had T for a long time and continued to go to shows without trouble, are not the kind of people prone to sitting around obsessing over every little sensation and change. That is, even if you go, protect your ears, and don't harm them physically... if it causes you to become more obsessive about your T and monitor it more, then it might seem like it's made it "worse" anyway, and this is a case where perception really crafts reality.
Because I am also prone to rumination, I don't go to shows the way I used to, by a long shot! I also wouldn't let my ear stuff hold me back from one if one of the handful of bands that I've followed for decades happened to be playing near me... but that's a personal decision (and if it turned out to be an "unreasonably" loud show, I would definitely turn around and leave). Point of fact I think I've been to maybe a half dozen concerts in the half dozen years since my T became an obstacle, and prior to that I probably went to one a month.
