Symptom recognition

 * In the Canadian Consensus Criteria, pain is a required symptom for diagnosis. It requires that "there is a significant degree of myalgia. Pain can be experienced in the muscles, and/or joints, and is often widespread and migratory in nature. Often there are significant headaches of new type, pattern or severity."
