Chills are common, but often are not related to an underlying disease. The most common cause of chills is simply being cold (shivering). Most people with chills due to a disease also have a fever.

Physicians will often search for a more specific starting symptom for a patient who complains of chills. This is because chills are a very nonspecific symptom. The first thing the doctor will do when you complain of chills is take your temperature.
