Cheek piercing, help?!?

i got my cheek pierced 5 days ago and i've been taking care of it and it doesn't hurt more than it should and the swelling on the outside has gone down.

the problem is that the skin on the inside of my cheek has started to grow over the ball. is my piercing getting rejected? what should i do?

will the ball come back if i wait a couple more days for the piercing to heal?

*i went to see the piercer two days ago when the inside swelling was getting pretty bad and she said that she had already used one of the longest bars on me and that the swelling was normal. (she was so wrong and today's her day off, which is why i was hoping someone could be helpful)
