Idk what's wrong..

I woke up this Morning and the Left side of my back hurts when I inhale * I can't even take a deep breath without it hurting..and when I turn.. It's like a stabbing pain. I woke up like this and don't know what to do.. I work later on today, but I want to go to the hospital to make sure I'm ok.. Am I doing to much? Should I just wait and see if it goes away first?
