Is it okay to change earring studs when the original ones have started to turn green at the back even if it may be earlier than the recommended four to six weeks for healing time before changing studs?

"If it has been at least 2 weeks, you can change them quickly. Just remember not to pull the ear lobe as you put an earring in, push it straight in.

Personally, from experience.. the green in the back of the earring stud isn't much to worry about and is closer to the piercing just actually healing...."

You're completely wrong, however here's the right facts towards body piercings.

The first mistake you had was getting pierced with a gun, or very low grade jewelry since the "green at the back" is the metal tarnishing because of it's low quality. Earlobes take 6 weeks to heal, however you don't want the tarnish to get into your fresh hole still.

I would say change it, it's not recommended in any professional sense to change jewelry early, but it definitly has to go if it's causing that.

Goodluck to ya.
