A little over a month ago, I went on a trip with my family that involved flying for over ten hours at a stretch. Besides the fact that the flight was long, it was uneventful. Since it was already late by the time the disembarked, we spent the night in that city. Early the next morning, we had to take a flight out to get another city, where we took yet another flight to our final destination. Exhausted, I fell asleep almost immediately we boarded the last plane but was awakened, after a while, by sharp pain in my ears. This wasn't the usual strange sensation I get sometimes in my ears in airplanes and which cleared up with ear-pops when I swallowed or yawned. This felt more like there was intense pressure in ears that were blocked and that hurt a lot. As if the pain wasn't enough, my hearing started to go gradually. That was very scary. Initially, I could hear muted sounds of people chatting in the airplane but even that gradually faded till I could barely hear a thing.
