I have a very serve fear of pressure changes; anything that causes suction or popping of the ear, or puts force on the eardrum. For instance: Changing elevation Putting my head underwater Shutting a car door too quickly Putting objects in my ears or covering my ears (including sleeping with pillows) Ear infections Yawning When I was very young I had tubes in my ears, so I never experinced any of this under I was much older.
