for about 4/5 weeks after it's been pierced, sometimes longer :L it depends on what it looks like i guess, like, if you can tell it's infected or still swollen, keep cleaning it, and if it doens't look any better, go to your piercer.
I doubt its safe for anything to go inside a lip piercing. Unless its healed.
That might and probably is a sign of infection make sure you clean it
Listerine should make it sterile and should clean the site
any body can get a lip piercing as long if its a unisex or male stud or jewelry
Sea Salt Spray
Salt water or saline solution on the outside of the lip around the piercing. Alcohol-free mouthwash on the inside of the mouth around the piercing
Go to the doctor. Right away, it means the lip piercing is beyond infected. Put antibiotic ointment on it and clean the piercing area properly. Remove the piercing right away, You might have to get your lip re pierced at another time.
There are no limitations to what you can eat after a lip piercing.
For your upper lip, Left is a monroe piercing. The bottom lip could just be a lip piercing, or labret piercing.
NEVER take out your piercing if it is infected. Doing so can cause an abscess. The piercing will close and trap the infection inside
Becoming swollen and sore after getting the piercing is usually common. What is uncommon is the stud sinking into your lip. You probably need to go back to the piercer and get a different type of jewelry.
If the ball on the end of the bar has closed inside your skin you will have to get it surgically removed. There is no other way of getting it out without seriously damaging your lip.
