Seriously though if you have neck pains even after doing a lot of stretching and exercise with your neck then it definitely could be something more serious. my dad had severe back pains and ended up having his left foot go numb they found that his spine had built up an excess amount of calcium which ended up closing up around the nerves, they had to cut his disc out and scrape out all the excess calcium and then put it back in. a friend of mine recently had severe neck pains and ended up having to have a lot of work done on his neck which they ended up putting plates in to where he can no longer turn his neck. all I can suggest is do plenty of neck stretching daily if you haven't already been doing so.
