DUDDDDE! Your amazing; why? Well 2 reasons
A) Self expression/I love people with lip rings
B) Mine was done last week
For the pain, well not candy coating it, once your body goes out of shock (yes shock, you gotta bar/hoop shoved through your mouth) it's gunna hurt, and swell, but look amazing
Same thing happened to me, um stay away, FAR AWAY from spicy/ physically hot foods, its like pouring salt into an open wound (not really, I just felt like quoting the song I'm listening to, but it will be uncomfortable)
Give it a week or two (I lied, I got it 2 weeks ago), it'll be like a part of your body
I don't know the placement of yours, but for the middle with the stud, its a bitch to eat
Hope it helped, and suck on ice, eat/drink cold food/drinks, hope you feel better
