This probably sounds very strange, but whenever I am running water, such as bath water or filling up the washer, and I am standing in the room with it, my ear will consistently pop until I leave the room or turn the water off. It has also done this when I am around popping grease, such as cooking bacon, and even a few times when I crumple up a plastic bag. My ears also often feel stopped up. What is the cause of this and what can I do about it?
