I had my lip pierced once, but it was very painful for me so I took it out, because the lady who did it was stupid. She pierced it very low, when it's supposed to be on your lip line, thats why its call a lip piercing. The reason why it was painful for me is because when I ate I'd accidently bite it, and sometimes when I talk loud or move my mouth around it'd be painful. But if you get it pierced in the right spot you wont have any problems, personally for me, a small hoop is a lot comfertable than a stud, you wont even know its there if you use a hoop, and plus their cute :) The pain rating from 1-10, would probably be a 4 or a 5, cause I have a very high pain tollerance (which is a good thing). My advice, just when you go get it done, act cool and calm just relax, cause they'll ask you to breathe it breathe out, do it nice and slow just breathe and relax the whole time your there :) If it helps, you can watch videos of people getting their lips pierced at youtube.com, just type in search "lip piercing" and theres people getting there's done. On how to clean it: Buy mouthwash with NO alchohol in it, rince for 60 seconds when you wake up in the morning and before bed, and also everytime you eat or drink anything. You gotta clean the outside also with Dial Antibactirial Soap, clean it with a qtip 2-3 times a day and also Saline Solution, which is sea salt. Just clean the outside with a qtip 2-3 times a day, or you can buy your own sea salt in stores if you cant find Saline, take about 2 tspoons in waters, stir it and clean with qtip. & remember, only touch the piercing when cleaning it! Dont play with it constantly, only when it heals completely, because I used to always play with mine and I got this white pimple looking thing growing on it in the inside, but thats when I took the piercing out and it went away. & always wash your hands before touching it. and your wearing a hoop you gotta move the hoops around because it will get all crusty, and if you wear a stud, turn it, do this everyday while cleaning it, morning night during day, it doesn't matter. So I wish you the best of luck! :)
