When you are getting sick the symptoms usually start at the neck, but what if it is something more? The following site gives a good way to do a 'self-diagnosis' to see what might be happening to you: https://familydoctor.org/x2556.xml#7
That is a very good site to have bookmarked for future reference. I have always been paranoid about neck problems because they can lead to other complications like thyroid problems, etc. However, after browsing through the site, I am finding that pains in many other parts of the body can lead to serious problems as well!
