How do I make the pain from my braces go away?

Yesterday I went to the orthodontist and he put brackets on the teeth behind the teeth with the silver ring around it (I was like wtf?! No one even sees those teeth) anyway, I haven't eaten in a day and I'm so hungry but those teeth back there where I chew hurt more than my teeth have ever hurt before. Every time I try to eat it hurts so bad I cry (I tried to eat macaroni and it hurt.) I don't like jello or yogurt or anything like that. I just want my teeth to stop hurting. Please help me. :/

I have tried every kind of pain reliever and nothing works. I've also tried numbing stuff and it didn't work either.
