Chronic fatigue syndrome is a rare condition that is characterized mainly by chronic fatigue that lasts for at least six months already. The cause of this condition is currently unknown although some hypothesize that it is related to a previous viral infection. There are alternative names for this condition and some are considered subtypes of it. These include myalgic encephalomyelitis, chronic fatigue immune dysfunction syndrome, and post-viral fatigue syndrome. Chronic fatigue syndrome produces symptoms that are utterly debilitating, severely affecting the person’s functional capacity and well-being. Here are the symptoms of chronic fatigue syndrome.

The key symptom of chronic fatigue syndrome is persistent fatigue that is not related to physical exertion and cannot be relieved by any amount of sleep or rest. This is what primarily makes this condition impairing as those who suffer from it are always tired. For some people, even moving a little can take so much out of them and therefore they are confined to their beds. This also reduces the functioning capacity and activity level of those who are affected by it.

Aside from the chronic fatigue symptom, a person must also have at least four of the following symptom in order to be diagnosed with chronic fatigue syndrome: impaired memory or concentration, post-exertional malaise that lasts for more than a day, unrefreshing sleep, muscle pain, pain in multiple joints without inflammation, headaches that have different patterns or severity, recurring sore throat, and tender cervical or axillary lymph nodes.

While the symptoms stated above are based on the official definition of chronic fatigue syndrome, other people who have the condition also reported having other symptoms as well. These include abdominal pain, sensitivity to foods, alcohol, odors, chemicals, medications, or noise, bloating, chest pain, chronic cough, diarrhea, dizziness and coordination problems, dry mouth, earache, irregular heartbeat, jaw pain, morning stiffness, nausea, chills and night sweats, depression, anxiety, panic attacks, tingling sensations, shortness of breath, weight loss or gain, and visual disturbances such as blurring, sensitivity to light, eye pain and dry eyes.

Chronic fatigue syndrome is a very serious condition that should not be taken for granted. If you experience most of these symptoms, then don’t hesitate to consult your doctor for a diagnosis.
