Can you please help me with my lip piercing (It looks like it's growing a wart or something)!?

I am crying hysterically because I had it done in January and in the past few weeks the area around the piercing has because swollen and it looks like a wart! I don't know what to do or what it is......I'm thinking that this piercing is the worst mistake of my life! Please, please help me.....Please.
