I’ve had it for a couple of years now. Not sure of the cause, but probably a combination of:
-dry, often infected/inflamed ears (drs useless)
-Peri menopause
-stress (difficult ASD teen)
It’s better when I’m less stressed, and I’ve gotten used to it a bit, too.
I was very interested to read what a PP wrote about carbs! I’ll be investing and experimenting with low carb solutions.
