Hi, I Stretched My Right Arm Behind My Neck And

Hi, I stretched my right arm behind my neck and then my neck on the right made a squishy noise and now it hurts with tension on the upper back part of my neck. This happened about 45-60 minutes ago and it's still not better and I've tried to extend my neck to where it hurts but it's too much pain. Is there any way I can stop it and be able to completely move my neck freely again?
