Nipple piercings are done by licensed tattoo shops. A person getting a nipple piercing can have a topical anesthetic applied beforehand if they are worried about the pain, which is rubbed into the skin fifteen to twenty minutes before the piercing is done. Nipple piercings take a long time to fully heal, up to an entire year. In addition, they can be easily aggravated or upset if the nipple ring is yanked on or accidentally pulled, causing inflammation and tearing to the skin. Women also might find that their nipple piercings hurt during their period, as the breasts can swell at this time of month and press against the nipple piercing.
