What's this pain in my chest?

I've started to have this sharp pain in my chest and it won't go away. It's around the middle of my chest on the breast bone and rib cage. It hurts when I sneeze, cough or just move around. It's a sharp pain and it has me on the verge of tears. Is this a serious issue? Should I go to the doctors tomorrow just to make sure it isn't serious? Thanks. :(

Thanks =P I feel stupid for asking this over the Internet but I just wanted to know if anyone had this before and what you did to treat it. I'll just go to urgent care first thing tomorrow morning and get an x ray. My mom is taking me.

Turns out it was inflammation around my rib cage. Thanks to those who answered.
