Even though I never talked to anyone about this, I feel like this happen to a lot of other people so hopefully I’m not wrong.
Like you know when you have a cold or allergies and you blow your nose inside a tissue but you do it slightly too hard and it feels like your hearing is diminished for a few seconds (kind of like when the plane takes off on a flight and you hear that POP inside your hear)?
Does anybody understands what I’m saying and knows why that happens?

There’s a tube that connects your ears to your nasal cavity. It’s how your ears drain fluid. So when you blow your nose you are pushing air back up this canal – essentially filling it with air. When you stop blowing your nose the pressure drops and the air is released.
Simple answer Pressure. When you blow your nose the air pressure generated presses on all zones equally until it finds an area of least resistance and then that becomes the pressure vent. So when you blow your nose, a good portion goes out the nostril, but a small portion of that pressure run through the Eustachian tubes into the ear. This can carry with it fluid from the sinus cavity.
PS Never hold your nose and blow, this forces all of your sinus junk into your ears and can cause permanent hearing damage from the pressure alone. Yawning opens Eustachian tubes which is why we yawn on planes. It allows the inner and outer ears to equalize pressure.
