12 hours ago I spontaneously dislocated then relocated my shoulder. Help please!!!!!

All I did was take Alieve afterwords. I was doing overhead dumbbell press, shoulder popped at full extension, arm came crashing down, thinking it was a cramp I rolled my shoulder and it popped back in. That was 12 hours ago. I feel like I should do more for it. It hurts a bit. Help?

(Sorry for title's exclamations, I don't know if this is severe.)
