I want to get my belly button pierced for the second time.. I first time I got it.. It got infected so I took it out because it was sooo bad.. Now it's been almost 2 years later and I'm getting it done again.. Is it OK to pierced the same scar tissue again? Should I get a barbell again or get a hoop (the rents think I should get hoop).. If I was to get a hoop piercing can I change it to a barbell in the future? Please help!!
