"Airplane ear" (ear barotrauma) can range from a mildly annoying "clogged" sensation to excruciating, sharp pain that feels like a needle being pushed into the eardrum. For most people, the pain is a dull pressure that occurs during the descent as the cabin pressure increases faster than the middle ear can equalize. However, if you are flying with a cold, sinus infection, or allergies, the Eustachian tube may be completely blocked, leading to a vacuum effect that can cause the eardrum to bulge inward. In severe cases, this can result in temporary hearing loss, intense vertigo (dizziness), and even bleeding from the ear if the eardrum ruptures. The sensation is often described as a "tearing" or "cracking" inside the head. To prevent this, experts in 2026 recommend using "EarPlanes" (filtered earplugs), the Valsalva maneuver (gently blowing while pinching your nose), and staying awake during descent to ensure you are swallowing and yawning frequently to keep the pressure equalized.
