please help me out! :/

just over a year ago i went & got both of my cheeks pierced.
they were fine for about nine months until lots of trouble started.
one of them fell out while i was sleeping & closed up while the other one started behaving really badly, i continued to clean it twice a day with a sea salt mix like i had for the last nine months but it didn't help at all.
i went back to the place where i got it pierced but what a surprise, it had closed down.
since then it has started to reject from my cheek, it's not red or angry, it has no discharge & it seems to have stopped rejecting. but the problem is it's stuck in the middle of my cheek. it has no exit hole on the inside of my mouth.
i have no idea what to do. D:
please help!

By the sound of it your cheek has enveloped the jewellery due to the bar being too small for swelling. What you'll need to do is go see a doctor and get it checked, they will probably have to cut it out.
