Help me, my neck is hurt in a weird way, i think paper is inside my neck?

some dumb mean kid spit out the sharp end of his fun-dip wrapper and it hit my neck now that area of my neck is swollen and itchy, and it isn't healing. I think some paper is in my neck, it fells like it, is that possible. a few weeks latter the kid burped a my neck and blew into the wound and it hurts even more. i am beginning to think that this kid went online and found out how to get paper stuck in the skin. is that possible if so could a doctor get it out? please help me
