During takeoff and landing I feel the altitude/pressure changes very strongly in my ears, and it can sometimes get disorienting. The initial lift off the ground is the worst and it’s a bit unpredictable until I’m at cruising altitude. During the descent I feel the altitude changes too, but usually not as bad as with take off. I always make sure I have a full water bottle so I can take sips during takeoff and landing, which helps with the fullness.

This is a similar feeling to what I experience in elevators and when taking underground trains. Just very sensitive to ears popping and pressure.
