I'm fairly certain it was about 2 years ago, but I suffered a ruptured ear drum and had to take off about a week from school. The pain was absolutely indescribable--it was the worst pain I've ever felt in my life. My ear frequently had blood and other liquids pouring out of it, which meant that I had to sleep on towels instead of pillows. I was put on various different meds and I healed within due time. Still, the pain was horrific and I hope I never experience anything like it ever again.
