Hi,
I've had the same symptoms and this is what it was for me (found out from dentist, confirmed my suspicions)…jaw clenching due to dehydration and anxiety….at night…clenching my jaw in my sleep (he said it's more common in woman)…leads to facial fatigue, soreness. I sometimes notice super fatigue in my chin too, but (again) only when I'm stressed.
