Hi everyone. Yesterday I was at the walk-up ATM and someone thought it would be funny to rev their engine next to us and the engine ultimately backfired (luckily it was farther away and not right next to us when backfiring). It was still pretty close maybe 20-25 ft away. I immediately covered my ears as soon as I heard the first "shot" so it was for about a second of exposure. My right ear felt slightly muffled, but has since felt mostly better. I was pretty upset and still am irritated over the whole thing. I feel because something happened I'm paying attention to my tinnitus more and keep going back to that incident wondering if it did any permanent damage, or if this will pass. I have been taking NAC and magnesium and staying in a quiet area. I'm just wondering if anyone has had a similar experience or any advice. Thanks!
