well its usually not that bad.
when i had it, i found out a tick went INTO my knee (way nasty) and i didn't find out until a year later. my knee kept cracking like a knuckle all day then it wouldn't move. then i was on crutches for a few weeks and my mom had to go to school with me to bring my backpack in. it was SO embaressing! luckily she only had to come in in the morning before homeroom. but with pills, it finally got better.
so i think you're going to be okay

btw: if someone asks if your going to die, say no; you wont die
