You've probably read about chronic fatigue syndrome symptoms such as fatigue, pain and exercise intolerance, but the list of possible symptoms of this condition are far-reaching and body-wide.
Many of these symptoms also can be caused by other ailments and you should discuss all symptoms with a doctor to rule out other conditions. This list isn't intended as a diagnostic tool. This list includes only those symptoms that you can detect yourself, not things for which you'd need a medical test. It's intended not to take the place of a medical diagnosis, but to give you valuable information. Knowing the full range of symptoms can help you track them either to help your doctor diagnose you properly, or to help you identify things that make you feel worse.
- Learn how doctors diagnose chronic fatigue syndrome.
- Find a doctor who treats chronic fatigue syndrome.
- Track your symptoms.
Some of the following are noted as overlapping conditions, which means they commonly occur with chronic fatigue syndrome but actually are conditions that need to be diagnosed and treated separately.
People with chronic fatigue syndrome may have flare-ups and remissions or may have constant symptoms with very little day-to-day change. You can have any combination of the following symptoms, and to varying degrees of severity. (Symptoms with an asterisk are included in the CDC diagnostic criteria, which is somewhat controversial. Many researchers and advocates are calling for the U.S. to adopt Canadian diagnostic criteria.)
