Could neck pain be a symptom of ALS? Sure—if you overwork your weakened neck muscles (and they'd have to be weak from ALS), they could hurt. On the other hand, neck pain is way, way more likely to be caused by poor posture, stress, and a whole bunch of other things. Kind of like stomachaches: bad abdominal pain can be a symptom of colon cancer. Do you really think that everyone who has abdominal pain has colon cancer? Not a chance.
