No. I had one too when my lip piercing was still healing. It's scar tissue and will go away as the piercing heals.
The side you want it on, there are no left right rules for lip piercing.
yes it will after a while i had the bottom side of my lip pierced and re pierced about four times now, at first it left a dark mark were the piercing used to be but now its just a small hole...barley noticeable.
I doubt its safe for anything to go inside a lip piercing. Unless its healed.
Go to a doctor.
you can do a lip piercing yourself although i do not recommend it for sanitary or infection prone purposes you may also go to a tattoo parlour and have it pierced there.
Yes it will. Don't play with it and be very careful not to hit it. You can also suck on some ice to help.
Go back to the piercer. it will have to be repierced.
Your piercing is infected and you should remove it. You should go to a doctor to get a prescription so the infection goes away and so you do not get very sick.
There are no bones in the lip. Body piercings do not go through bone, only skin or cartilage.
Go see a professional body piercer.
It depends on where you go to get it pierced.
