How do you heal an infected lip piercing with out going to a doctor?

Infection isn't something to play with. If you have an infection, go to the doctor. You're gonna need antibiotics so you need a prescription from a doctor. Walk-in clinics are an option if you don't have a doctor that you visit regularly. If you try to treat the infection on your own and it spread, you could run into major problems, sepsis being one of them. Don't risk spreading the infection or facial scarring to save a few bucks. Go to a doctor as soon as you can to clear up the infection quickly.
