I don't really think so, chlorine isn't good for a piercing (if you're swimming in a pool) and salt water, even though helps heal and get rid of infection for piercings, can always have a lot of bacteria in it (and fish poop). My suggestion is, don't go swimming until it's fully healed (which can take 6-12 months to heal unfortunately :/).
A belly piercing is a piercing on the belly button. Where your belly button might go in or out, it is the slight arch you get just above it. it is a piercing through that area. depending on how your belly button is formed. Search google for images.
Go to your doctor.
Go to the ER.
Yes. Just wash the piercing out once you are done.
To a professional piercing studio or to a tattoo shop that offers the service.
You need to go there in person no prices on the internet
it is if you just got it buy if not go get that checked
Pus indicates an infection. Go see your doctor right away.
There are no specific odds of getting your belly button piercing infected. The odds of getting your belly button piercing infected go way down if you wait until the piercing is healed before you go swimming. It is important it does get infected that you see medical treatment immediately.
You'll have to go into the piercing shop and ask them to look at it. Everyone is different so they'll have to decide.
No you shouldnt. the chlorine in the water can over dry a new piercing.
Just buy regular salt, or you can go back I your Piercer and get something.
