No they don't numb the needle. It doesn't even hurt it just burns a bit. Remember no smoking or drinking till it heals.
Nope. They just pierce it. Anything they could use to numb your lip would cause it to swell up, making it hard to pierce you accurately. Besides, it doesn't hurt very much.
It depends on the shop. Some shops do it, some don't. It's just a lip piercing, only takes a second, you can do it :]
Yes there are veins in your bottom and top lip.
No, it is illegal to numb lips as the stuff could get in your mouth and the chemicals can poison you.
Monroe piercings can be numbed using a freeze spray on the outside of the lip and an oral numbing spray on the inside of the lip.
If you have a overbite it can cause the lip to stick out more than the bottom lip. You can go to a dentist and have them look at it.
At a professional piercing parlor, they usually don't. You can actually easily numb the area yourself by holding ice to it for 10-20 minutes before (maybe even less). There are creams you can get from your doctor, but they might not be good for the lip.
I knew this guy that pierced his lip hisself and hit a nerve and a large part of the left side of his face is permenantly numb. I pierced mine 4 times, and it turned out fine, but i guess i just got lucky.
They may still have feelings for you... or they may not know how they feel about you now
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.
