I have done them all by myself and never had an infection (tongue, lip, nipples, eyebrow, 6 in each ear, top and bottom belly button
and my nose) have never had the white thick discharge
except for a piercing that i have taken out to close it up. my nipples have just gotten redone after my pregnancy, I had my doctor do a look over to make sure it was ok to breast feed. He told me that there was nothing wrong with my nipples and it would not effect breast feeding.
