I want to get my nose pierced

It didnt hurt much because I did it and I am not a shove it through quick kinda gal, more of a visualizing the flesh moving away. I didn't swell but I had problems with infections. I am sensitive to metals (even gold) and once I switched to a monofilament retainer it was great. They make clear acrylic nose screws with jewels that I would recommend for the many moons it takes for the nose to heal. I have too thick of a nose for a nose bone so I would have to tweak the curve on the metal ones I had and they never quite fit right.
Not sure about the breastfeeding issue other then you can never be 100 percent sure you are not going to contract something from a needle someone is handling (that is why I did my own...oh and it is much cheaper too).
Take tylenol for the swelling and pain, keep it clean by rinsing with salt water, don't touch it unless you have just washed your hands, keep it away from fabric as having it ripped out when you aren't expecting it sucks ass. Tea tree oils helps disinfect it.
