piercing bump on my nose!

I don't know if this is the right place to put this but we'll just wing it lol 
Okay so I have a friend that has a piercing bump on her nose. She's had it pierced since October and it won't go away. She cleaned it how you're supposed to for how long you're supposed to, changed her nose ring to a real gold one incase she had a metal allergy like I do, and it's not infected. I suggested that it might be her body rejecting the piercing but I don't know. Anyone have any suggestions on how to get rid of it?? 
Update!!! 
She just took it out. If she wants it again she will just get the other side done. 😊
