Earwax is a waxy substance secreted from the ear canals of humans and other mammals. Removing earwax from adults is fairly easy, but cleaning earwax buildup in children is more difficult because their ear canals are very delicate and require careful handling.

Ear pain when flying is also known as ear barotrauma, which occurs when your eardrum is stressed due to an imbalance in the air pressure in the environment and the air pressure in the middle ear. Therefore, when sitting on a plane, you often experience pain and earache.
