Seems like possible triggers include certain noise levels/frequencies, stress and/or blood pressure, and fatigue.

But not really figuring out a rhyme or reason. Fortunately at its worst it never seems to last more than a few hours, maybe a day max.

But as many have stated, your mind just moving to other things helps even when it’s bad. Figuring out that it’s possible to cope is the biggest help of coping and getting through the tougher hours/days.
