Chills and rapid body temperature changes are usually a sign that something is not right. Influenza and the common cold also cause these symptoms.

It isn't even the most common cause of temperature fluctuations. But any out-of-the-ordinary signs such as these are enough to see a doctor for. Be especially concerned if they last longer than the few days it usually takes to get over a cold or flu.
