I was flying back to school once while I had a sinus infection that I was getting over. I fell
asleep during the ascent. When I woke up, I couldnt feel the top left portion of my jaw.
Teeth and everything. It was way fucked up. After about a minute of freaking out in my
head while trying not to appear crazy, I figured out it was because of pressure that had
built up in those sinuses above my jaw due to the ascent and the infection.
It took me another five minutes to actually get my ear to pop. Within prolly ten seconds
all of the pressure was gone and my jaw was back to normal. I wasn't entirely convinced it
had actually happened for a couple minutes. Weirdest experience I've ever had flying.
