so there's a place in OKC that looks VERY clean, they have a virtual tour on the computer with all rescent pictures and u can pull the pics around to view the entire room. It's pretty cool. Anyway. I think that's where I want to go to get my BB done. Now it's off to ask my mom about it but anyway back to the question. I have a total of 7 piercings in my ears.
compared to ears how bad does the belly button hurt.

( I have 3 in the lobe of each ear = 6 and 1 in the cartlidge of my left ear = 7)
the ears didn't hurt at all and I asked a lot weither or not she was going to pierce my ears and she told me she already did... granted afterwards they kind of burned a little but no biggy.

from that on a scale of 1-10
10 being the worst. How bad would it hurt?

It depends a lot on the person, but if you have a cartilage piercing you can stand the bellybutton one, I'm guessing. Ask to see the autoclave and the unwrapping of a sterile needle if you're not sure about the place, I've never been so I know nothing about that place.
