Suggest Treatment For Swollen Face And Lips After Face Piercing

I got a monroe facial piercing on Tuesday. Friday morning when I woke up, the half of my face that the piercing was on was swollen, especially my lip. I went back to the piercer who gave me a longer bar and the swelling went down. I took out the piercing later that night. Since then the swelling has been going up and down and I also have an itchy rash on my face. I have been icing my lip and taking Iburofen, what else can I do? Half of my lip is huge, and I don't want this to be permanent!
