I got two lip piercings done two weeks ago (snakebites), and one of them has gotten a bit swollen again. I’m guessing it’s merely irritated as my other piercing is fine, plus it happened while I was eating and the bar got caught on my teeth + irritated while sleeping, anyway, it was swollen and bled a little when I woke up.
How would you tell the difference between an irritation and an infection?
