Why do we experience pain in our ears during changes in altitude?
Step 1 of 3
Pain in the ear at high altitude is a pressure pain. Normally, the pressure inside the ear, and in the ambient environment is equal. The ear is closed to the external environment at the eardrum, but connected with the pharynx (and the oral cavity) via the eustachian tube. It is through this tube only that the pressure can be equalised. This happens routinely while swallowing and yawning as the tube opens up in these actions and the air in the ear and in the mouth gets connected at the same pressure (Which is also the pressure outside). At high altitudes, the pressure outside is less than the inside of the ear, due to these pressure differences, the tube fails to open, the pressure difference...
