I Woke Up Saturday Morning With What I Thought Was

I woke up Saturday morning with what I thought was a "crick" in my neck... I've had them before so I applied heat to it... It has gotten worse... Now I can't even move or turn my head without an acute pain practically paralyzingly me... My husband thinks that it could possibily be a pinched nerve... Heat or cold doesn't seem to help... What do you suggest? It even hurts when I swallow,,
