Anxiety and stress can cause pain around neck, shoulder and chest because stress related body readiness mechanism stretches muscles. Such stretching could create muscle soreness and after some time, there will be pain. If you are anxious, such pain will be obsessive, and you will become more anxious about it. Heart attack has other more important symptoms than this. In any case, you should consult a physician and get your EKG. They will explain to you everything. Don't worry.
