I'm pretty sure it's from extra adrenaline or cortisol or something that is floating around.
The more you focus on it the more you get and you create an endless cycle.
Once I learned that it wouldn't kill me and it's not dangerous and I just let it be, it got less and less and/or I don't notice it unless I think about it. Kind of like tinnitus (ringing in the ears).

I also have it a decade.
