don't pop it and consult a doctor.
Sounds like it just might be tissue or cartilidge in the ear that moved. She could always call the place she had it done if she is really worried however if it's not sore or anything I honestly wouldn't worry to much about it.
I cleaned my upper ear piercing with hydrogen peroxide to keep infections away. If it fizzes and bubbles up its killing all the germs that are infecting her ear.
Its completely safe too. So no worries. I'd try it just as a safety measure.
It is called a Keyloid and it is scar tissue that has built up around the hole. I have had this happen. Some people are more prone to them than others. I suggest taking out the piercing otherwise it can get bigger. Once I removed my jewelry it went away.
