I got my seconds percided about two and a half months ago, when the starter stud was taken out I put sterling silver studs in but they tarnished in a few days and started getting crusty so I opted for gold studs so now I have good studs for my seconds and a small hoop for my original one and I think my seconds are starting to get infected, any tips on how to help an infected piercing or to prevent this from happening? (I'm 14 btw)
