I have had several piercing (ears, lip, bellybutton) over the years and I have an extreme sensitivity to metal so I've taken most out. Even yellow gold and the surgical steel will bother my ears after a while. I finally got some of my piercings to heal correctly (my ears have been a problem since I was a little kid) by following the instructions of a piercing shop very specifically. I clean mine twice a day with an anti-bacterial soap like Dial. I soak them in sea salt water if they get at all irritated for about 15 minutes once or twice a day until them clear up.
I have to wear nickel free metal if I wear the same earrings for more than one day. If you can get her to heal up well enough to take them out at night let her sleep without them. Do not use Neosporin, hydrogen peroxide or rubbing alcohol. All of these can slow healing and are not recommended for tattoos or piercings. If she's in pain you can contact a piercing shop to ask for gel lytocain to put on it. Some of them will carry it but you may have to go to one that’s also a tattoo shop not the place at the mall. If you’re anywhere near Roseville let me know and I can recommend a good shop to you.
Good luck!
