He nodded, eyes watering. The plane decelerated, and with the change in speed, a tiny, wet pop occurred deep inside his head. It was not a relief. It was the sound of a small, internal dam breaking. The muffled world snapped back into sharp, painful focus. The engine roar was now deafening. A baby’s cry three rows back was a spike in his skull. His own heartbeat thrummed loudly in his right ear, a bass drum played just for him.

In the taxi, he didn’t speak. He just watched the city lights smear across the window and listened to the strange, filtered version of the world. He tried the Valsalva one more time. A small, clear pop . The hollow echo vanished. The taxi’s engine settled into a normal hum. The driver’s muffled radio became music again.

He tried the Valsalva maneuver—pinch the nose, close the mouth, blow gently. A small, pathetic squeak answered him, like a mouse stepped on a floorboard. His left ear was fine, crisp, alive. But his right was now a world of cotton and muffled whispers. His own voice, when he said “excuse me” to reach for his water, sounded to him like a man calling from the bottom of a well.

Descent began. The seatbelt sign chimed. Leo felt the plane drop its nose, and with it, a clamp of pain tightened behind his jaw. It wasn't sharp, not yet. It was the ache of a stubborn vacuum, a tiny, stubborn god in his eustachian tube refusing to open its temple doors. He swallowed repeatedly, a dry, desperate clicking in his throat. He chewed the gum he’d bought specifically for this purpose, now a flavorless wad of desperation.
