Valsalva Maneuver.
“The Valsalva maneuver is a breathing technique that can be used to unclog ears, restore heart rhythm or diagnose an autonomic nervous system (ANS). To perform the Valsalva maneuver, you should close your mouth, pinch your nose shut and press the air out like you are blowing up a balloon.”
There are add ons to it, such as ice on the back of the neck and pressure applied to the eyes.
