Neck is sore and right arm numbness.? - sore neck snowboarding

Snowboarding was three days ago. jumped and fell on his back and heard some cracks. Do not feel so bad at one time, but the next day I had pain in the neck, then sing a lot and my arm was tired and now feels a little glory. I just want to know if there could be a serious injury or improves with rest and relaxation.
