This is the second time I've noticed this. I've had a few piercings since I was young. I got a batch of piercings a while ago and the old, established piercings started to ache and ooze along with the new piercings. All seemed to be better and I got a few more piercings recently. Now all of my piercings, including the last batch are sore and crusting. Can my new piercings cause my older piercings to be irritated? Thanks, S.
