Intense shoulder pain after sleeping please help?

Ever since waking up this morning, my shoulder (lateral deltoid) has been in a world of hurt. I can't raise or straighten (push) my arm forward and do any side raises without sharp pain and loud cracking of my shoulder. While that happens, I am also getting some pain down the triceps into the elbow joint and numbness from the elbow joint to my hands and fingers. Whats wrong with my arm?
