Below is some correspondence with a gentleman who was having trouble healing his second set of nipple piercings:
First off, I want to thank you for all the things you've done for the piercing and body modification community. You are truly a pioneer and have helped so many of us along our journeys with your work and writing.
I have been having some trouble with a newer nipple piercing and have been unable to resolve the problems I've run into, so I figured that I would turn to the most knowledgable person I know of when it comes to piercings, you.
About two months ago I got my nipples pierced a second time, I already had a set of well healed and toughened horizontals for years. The piercings were done complication free, tucked right behind the existing horizontals at the base of the nipple, possibly ever so slightly into the areola. They began to heal relatively problem free and I commenced with my usual aftercare of daily Provon washes and twice daily sea salt soaks.
