Muscle spasms . Even young people can start experiencing neck problems due to neck nerve root irritation. This can occur because of lifting heavy things, sports injuries or other accidents. Repetitive stress injuries can also initiate the symptoms, sleeping on the stomach with the neck twisted to one side can kink the neck nerves. Drinking cold liquids can initiate muscle spasms. See family md for treatment.
