In a car accident yesterday, whiplash?

I was in a car crash yesterday where the car pretty much bounced on both sides and i was in the back, wearing a seatbelt but my neck got thrown back and i winded myself as i couldnt breathe for a tiny bit. I'm fine now and so was everyone else, but my back really hurts between my shoulder blades and it has been since immediately after the crash. It's not bothering me too much, so will it just go away in a bit? or should I get it checked out? (i'd rather just leave it but just wanted to check it won't be dangerous) thanks
