The symptoms of chronic fatigue syndrome (CFS) vary widely between individuals but usually symptom onset is sudden, with an affected person becoming persistently or frequently tired for no apparent reason.

Diagnostic criteria are based on a pattern of symptoms which are observed over time as no one symptom or laboratory test can confirm a diagnosis of CFS. The Centers for Disease Control and Prevention recommends that a diagnosis of CFS is considered when the fatigue is:

Unexplained, new and persistent or recurring
Is not relieved by rest or sleep
Interfering with activities of daily living

In addition, one of the following features should be present:

Sleeping difficulties such as insomnia, over sleep, disturbed sleep
Muscle and joint pain across multiple sites that does not seem to be caused by inflammation
Headaches
Painful but not enlarged lymph nodes
Sore throat

General malaise or flu-like symptoms
Dizziness and/or nausea
Palpitations but not cardiac pathology
