Infected nipple ring

Li

Hey girls! I was looking for some advice. I got my nipples pierced almost 2 years ago. The right one has never healed. It would randomly just hurt. Never bad always tolerable. But recently i noticed when i was in the bath there was pus, which i’ve noticed before. I just thought it wasn’t healed all the way still. But then i went swimming and now my nipple is extremely swollen, but it doesn’t hurt at all. I just was wondering what to do. If you think that i should take it out. Please let me know. I’ve had these pierced for awhile now like I said.
