Does getting your belly-on done hurt alot?

I have wanted my belly-on pierced on the top only for agess, and my friend got it done last Wednesday, I asked her if it hurt, but she didnt describe it very well, she kept on contradicting herself..Does anyone know how much it hurts? [Btw, please no yes/no answers, gory details would be nice :P] Also, does anyone know what they do, and how long it is before you can change it or take it out? And what do you do with it whilst in the shower? And also, I have searched these things, im serious and dont want it to get infected, i just want to hear from a real person, not a leaflet, also, they all say different things :S Thankkssss x
