:confused: I got my navel pierced and it is infected I think...
Well it started with a crusty stuff around the piercing and now it has started pussing... :(
I don't know how to get the infection out, Please help me someone!!

Wash gently, and wash again. Use 3% peroxide to gently wash the area and move around the piercing so it gets treated all over. You weren't clean enough or not informed well enough to have a piercing in that area. Call them.

Usually peroxide isn't good, but in the case of an infection it may be good to get all the infection out.
Call your piercing, or go in to see them for advice.
Or go to your doctor, and ask if you can get something to treat it, though they may want you to take it out. Where you run the risk of trapping the infection in.
