i got my nipples done about 3 months ago give or take a few days. my left one healed fine, but the right one is still sore and has two small lumps on either side where the barbell comes out. it still gets crusties on it too. ive been trying to take care of it well, but i think either it has a minor infection or it's starting to keloid or both. what can i do? how do i know which it is? also, i really want to put nupercainal on it. can i?
