I can't breathe or move. Help! Please!?

My back started hurting like 10 minutes ago and rapidly it got worse! It's my upper back and now I can't move an inch without screaming!!!!!! And it hurts to breath! So I gotta take the little itty bitty breaths. Is this a pulled mustle or something? I took a flexril. Or could it be something worse. To top it off I have the hiccups and it's killing me!!!!!!!!!!! I'm using my phone cuz I can't get up to go on the computer.
