When a plane changes altitude rapidly—especially during descent—the air pressure in the cabin changes faster than the air pressure inside your ear. This creates a vacuum that pulls the eardrum inward, stretching it and causing that dull, blocked sensation. Immediate Remedies to Clear Your Ears

If the blockage is causing discomfort or feels like fluid is trapped, place a warm, damp washcloth over the affected ear. This can help reduce inflammation and promote drainage.
