I used to be a tattoo artist
and worked beside pro piercing for years.
For any new piercing, or one that's giving you redness,
swelling or pus:
Wash the site with LATHERED antiseptic soap.
Spin the jewelry.
Rinse with water.
Rinse with saline.
Apply a healing oil.
(I dont advocate for use of mineral oils
or petroleums on skin...I'd opt for tee trea or eucalyptus,
though that may be too harsh for some)
Keloids are a problem.
I remove piercings wherever keloids show up.
They usually go down a bit with removal of the jewelry.
check out some weird keloid stories on bmezine.com...
get there and search keloids.
Good luck
