You've had a hole punched in a area of your body that is not supposed to have a hole. And that area is one of the most bacteria laden areas of the human body. I would be surprised if it was not swollen. See your doctor to be sure.
Also when I got my tongue done I talked funny for about a week as well. It can swell up pretty big. But if it gets to the point where breathing is difficult then see a doctor, otherwise the swelling will go down. Everybody's different maybe yours swelled up a whole bunch. Also eat tomato soup, it supposed to help it heal says the lady that did mine back home.
