Ear and Altitude (barotrauma) occurs when the eustachian tube in your middle ear is blocked due to altitude or pressure changes, and air cannot be equalized, so a vacuum occurs. Ear problems are one of airplane travelers and divers’ most common medical complaints. While they are usually minor annoyances, sometimes they can cause significant symptoms.  The altitude change stretches the eardrum, which causes pain and occasionally fluid build-up. The common cold, sinus infections, and nasal allergies can also interfere because swollen membranes in the nose can extend into the eustachian tube and block it.
