It could be either due to neck or shoulder associated conditions. Better consult any specialized doctor for complete diagnosis of the pain. If the pain is not bothering u much during the day then apply heating pad .

Pain might have occurred due to incorrect sleep posture. Incorrect sleep posture can lead to pain and stiffness of neck muscles. Use special pillow that supports natural curve of your neck and also supports contour of your head. Don't use high pillows which keeps your neck bent. When you are lying on to one side make sure your spine is straight.
