I have fibromyalgia and wondered if chest tightness and palpitations were normal?

Chest tightness : Chest discomfort must be taken seriously. While it is possible that the symptom is from one of the many causes of chest pain that won't kill you, unfortunately it is very difficult to distinguish from the kinds of chest discomfort that can kill you. Concerning chest discomfort should be evaluated by a physician urgently. If it is happening now, go to the nearest emergency room.
