@coreo Yep, nipples. For the second time.
I had to take them out for an x-ray last time & then waited too long before attempting to put them back in.
The piercer told me to come in as soon as possible if anything like that happened again.
Ah well, even if I have to get that one done a third time, I'm at the point now where I enjoy the experience enough that I won't mind it too much. 😉
