my knee

In the ninth grade i got supper sick and was out of school for a couple of months, it sucked. when i was sick my body sent messages to my knee saying that it was infected, when it really wasn't. because it did this my body basically turned on itself and end result is this nasty fluid behind my knee cap. whenever it goes from being really hot out side to really cold outside the fluid comes back. The way they get rid of the fluid is by sticking a needle in your leg that goes up behind the knee cap and inject it, that really sucks too. anyways the reason im blogging about that to day is because its the season that goes from super hot to super cold and the fluid came back. so this morning i got the shot, but instead of just behing the knee cap it went into the knee cap and out of the four times i have done this today was the worst one ever.
