So my son blew an air horn right next to me for a about 2-3 seconds.
My ear feels kind of warm now. No pain or loudness in T yet. But hopefully this won't cause a spike or affect T. :/
Try not to worry about it. Easier said than done, but the worrying part is often the problem itself.
I had loads of spikes, still do, but nowhere near the veracity of when I was overly anxious about it all. My mindset, when it comes to tinnitus, has changed completely. I no longer fixate on it; I just let it be. It's simply acceptance. Once you stop fighting it and using all your energy worrying about it, your situation can and will change.
The tinnitus will back off; it's a perception thing but it's very powerful once you tap into it. It's basically the whole 'back to silence' thing.
I know this seems impossibly hard, it took me ages, but next time you feel concerned or worried when you hear the noises in your head, stop yourself. Let the noise be but DON'T react at all to it. Just let it do its worst and carry on with your day. This takes all the strength in the world to achieve but it can pull you out of the negative cycle you are stuck in. Once this starts to unfold you'll notice that there will be extended periods where you won't think of your tinnitus at all. In fact, as this progresses you can go days and weeks without thinking about it.
Habituation is not a myth. Train your brain to get bored of the signal and in return your brain will stop pestering you about it. A lot of people reach this state naturally, but the more anxious of us, i.e. us, people who sign up for support forums suffer a lot more with it.
There are countless people out in the real world who could tell you positive stories all day long, but unfortunately the vast majority don't randomly sign up to forums to tell you about it. You only read the worst case scenarios imaginable.
Stay positive.
