Wednesday I played my first gig in 8 months. All health professionals I spoke to said that I should be OK, only that I may notice an increase the following day, which would go away. I did about 4hrs of driving in total (3hrs with earplugs), did multiple soundchecks (w/ custom earplugs) and finally played two 1hr sets (w/ foam earplugs). All this time, I felt perfectly fine. The next morning, I still felt fine, but did notice a slight increase after 1hr of being awake. That day my T went from left ear only to both, and increased in volume a bit. It's now Friday 12:30 (PM) and my ears are still ringing louder than usual. The gig wasn't excessively loud at all, I wasn't worried about my ears, and I'm not panicking now either. Is there any explanation for this? You'd expect that an increase would be immediate, not after 36hrs or so. That's also what I remember from an event 13 years ago, having temporary tinnitus immediately after being exposed to loud music, which then went away soon enough. Complicating factors may be: slight braces adjustment on Wednesday morning; I've been under a ton of school-related stress over the last weeks; sleep schedule was disrupted (although I've caught up on sleeping now), and the gig itself meant lots of preparing/planning, and I was responsible for taking another two musicians with me in the car.
