[Yokuutsu]

like a little bit of sea salt to a cup of water-warm they say, but I've done cold.

You can soak cottonballs in it and just kinda let it sit there on the piercing....or spray it like I did. If you notice an infection-use the cottonball instead....and you might want to do the same with the inside of your nose-using the cottonballs (you'll have to work with them to get them up there.

Warm is best until the swelling goes down
