Hi, The restriction to neck movements can happen due to many reasons such as if you lifted anything heavy while working, using more pillows to sleep, sleeping in an awkward position or due to stress. Think hard and see if you have been part of any of the situation mentioned above. Once you find out the cause, if the pain and other symptoms are mild, I would advice you to start stretching, avoid strain, rest and apply moist pack to relax your neck and upper back muscles. Sleep without pillow for longer hours and do not lift anything for time being. Furthermore, if the symptoms do not subside or increase in intensity, please visit to a nearest doctor to check if there's anything else causing neck restriction.

Take a medical prescription for muscle relaxant and anti-inflammatory. This could be done on Practo. Visit a physiotherapist.
