I would notice that being in loud clubs throughout my 20's would not be good for it. It would aggravate it to a degree. In a few rare cases the ringing would come back to a higher pitch. Then it would fade away after a number of weeks. That's right, weeks, not days.
Long story short, I'd say at some point in the early 2010's my tinnitus became an absolute afterthought. Sometimes I would actually forget I had it. Then it happened...
My best friends wedding was July 15th 2018. You would think the DJ was playing in a nightclub of only twenty somethings. The music was insanely loud to a level that I hadn't heard in years. I would try and protect my ears as I did for so many years after my initial incident and kept my time on the dance floor to a minimal. However towards the end of the night, I must have spent a solid hour up there, just enjoying myself.
The next day I noticed it. I had aggravated my tinnitus to the point where the ringing was back full force. This would be the first time in many many many years I would experience this. The problem now is it is August 28th 2018, a month and a half since that night and the level of the ringing has not gone down. I am wondering if it ever will not or if who knows, maybe I have damaged the inner area of my ear for good.
