Fever

It's been a long time since I've done any poetry analysis. But since I've had a headache for days and I can't sleep because I have to work, I decided to bum around online a bit and find a good poem. And lucky me, I did! "Fever 103 degrees" has some real awesome imagery. I'm not exactly sure what the poet was going for though. Initially, I thought, "wow, this is a great poem about a headache," probably because of my own current physical affliction. Now I wonder if this poem is about anger. And why do I think it's so good when I don't understand what it means?
