certainly.
You can. I changed mine after a week and a bit and they are perfectly fine a month later.
You have to keep your earrings in for at least 6 weeks before you can take them out or change them.
for small secions of time
obviously they close up....what do you expect them to magically stay there?
Yes, you can but be Sure to put the ones your changing them with in hydrogen proxid.
When the six weeks are over you may be able to wear dangle down ear rings or hang downs.
You have to keep them in for 6 weeks, but I would suggest keeping them in for a little longer, as peoples lobes have different healing times, some could be....let's say 2 weeks, others 6 months! =) As an average for all people, I think you should wear the same gold-backed earrings for at least 3 weeks, then you can change to other gold-backed earrings. Wear gold-backed earrings for 2-3 months. If your ears don't look ready, wait another month or two. Finally, you can wear other earrings and your ears should be fine.
You are supposed to wait 6 weeks before changing them.
After 6 weeks.
6 weeks after.
mast people wait about two to three months so that it can complete heal over but one month is normally okay.
