I first got it in 2015 after playing Fallout 4 almost nonstop for the entire weekend. The game ran poorly and the low stuttery fps caused a massive migraine in my head. I took Tylenol and went to sleep and woke up with it ringing in one of my ears which eventually moved to both. The doctors were pretty useless and said they couldn't see anything wrong and to just live with it.
My brain eventually figured out how to tune it out and now it associates the sound with silence.
Now I've developed it again after feeling depressed and blasting music in my car. The new version crackles and alternates tones in my left ear. I have a doctors appointment coming up to hopefully figure it out.
There is a new expensive treatment for it called Lenore which works by playing sounds and stimulating your tongue at the same time. Those pathways are located close together in the brain and by stimulating both at the same time, it's supposed to train it to filter out the noise.

Unfortunately that is the truth of it. Sometimes tinnitus can be traced to other parts of the body, but more often it seems to be caused by the brain acting up. And we just don't have enough knowledge about the brain to fix things like that, so all you can do is try to habituate.
