Imagine this: you're off to some faraway place in an airplane. All you can think about it how excited you are for your trip. The plane starts moving, you look out the window, and just as the plane leaves the ground, you get a massive ache in your ears. Is it possible to avoid having the inside of your head explode every single time you take off? In order to find out how to prevent this, you first have to learn the science behind why you undergo this painful sensation.
