Piercing Infection

Hannah
So I got my lower ear lobes pierced a second time about three months ago. However, it seems like whenever I change the earring to one that isn't the earrings they pierced them with, my ears start bleeding and they get puss on the earrings, etc. I never had issues with my other lobe piercings, and I had them done when I was 11. I also have a cartilage piercing in my left ear, and I've never had issues with it either. I followed all the cleaning procedures recommended by my piercer, but I'm really sick of not being able to change my earrings to something cuter after three months. Any advice?
