Went for a belly button piercing a few months ago. Got it done mind you the guy didnt do it right so it was crooked. I had to ask what I should do for cleaning and when I should be able to change it. Said soap and water is fine and 8 weeks for it to heal properly. Well I have been having major pain in the belly button area (I still clean it and its not the starter ring) the whole for it is humongous and my skin is slowly ripping so its slowly falling out. They seem like they do good on tattoos just not piercings.
