Chronic fatigue sounds rough, it brings long term fatigue and limits a person to carry out daily things.
Chronic fatigue syndrome (CFS), also referred to as myalgic encephalomyelitis (ME), is a medical condition characterized by long-term fatigue and other symptoms that limit a person's ability to carry out ordinary daily activities.

Chronic fatigue syndrome
Chronic fatigue syndrome (CFS), also referred to as myalgic encephalomyelitis (ME), is a medical condition characterized by long-term fatigue and other symptoms that limit a person's ability to carry out ordinary daily activities. Biological, genetic, infectious, and psychological mechanisms have been proposed, but the cause is not understood. Diagnosis is based on a person's symptoms. The fatigue is not due to strenuous ongoing exertion, is not much relieved by rest, and is not due to a previous medical condition. Fatigue is a common symptom in many illnesses, but the unexplained fatigue and severity of functional impairment in CFS is comparatively rare.
Cancer-related fatigue
Cancer-related fatigue is a subjective symptom of fatigue that is experienced by nearly all cancer patients. Among patients receiving cancer treatment other than surgery, it is essentially universal. Fatigue is a normal and expected side effect of most forms of chemotherapy, radiation therapy, and biotherapy. On average, cancer-related fatigue is "more severe, more distressing, and less likely to be relieved by rest" than fatigue experienced by healthy people. It can range from mild to severe, and may be either temporary or a long-term effect. Fatigue may be a symptom of the cancer, or it may be the result of treatments for the cancer.
History of chronic fatigue syndrome
The history of chronic fatigue syndrome (CFS, also known by many other names) is thought to date back to the 19th century and before. Several descriptions of illness resembling those of chronic fatigue syndrome have been reported for at least two hundred years. In the 19th century, neurologist George Miller Beard popularised the concept of neurasthenia, with symptoms including fatigue, anxiety, headache, impotence, neuralgia and depression. This concept remained popular well into the 20th century, eventually coming to be seen as a behavioural rather than physical condition, with a diagnosis that excluded postviral syndromes.
Chronic fatigue syndrome treatment
Treatment of chronic fatigue syndrome (CFS) is variable and uncertain, and the condition is primarily managed rather than cured. Only two treatments, cognitive behavioral therapy and graded exercise therapy, have demonstrated reproducible evidence for their efficacy people with CFS who are walking. There are no Food and Drug Administration (FDA) approved medications for ME/CFS treatment, although medications are used without approval for the illness (off-label). Drugs have been used in experimental studies of the illness that haven't been approved for market for any condition in the United States (for example, isoprinosine and rintatolimod).
Clinical descriptions of chronic fatigue syndrome
The clinical descriptions of chronic fatigue syndrome (CFS) vary. Different agencies and scientific bodies have produced different guidelines to define the condition, with some overlap of symptoms between descriptions. Aspects of the condition are controversial, with disagreements over etiology, pathophysiology, treatment and naming between medical practitioners, researchers, patients and advocacy groups. Subgroup analysis suggests that, depending on the applied definition, the CFS population may represent a variety of conditions rather than a single disease entity. The most widely used diagnostic criteria for CFS are the 1994 research guidelines proposed by the "International Chronic Fatigue Syndrome Study Group", led by the Centers for Disease Control and Prevention.
Fibromyalgia
Fibromyalgia (FM) is a medical condition characterised by chronic widespread pain and a heightened pain response to pressure. Other symptoms include tiredness to a degree that normal activities are affected, sleep problems, and troubles with memory. Some people also report restless legs syndrome, bowel or bladder problems, numbness and tingling, and sensitivity to noise, lights or temperature. Fibromyalgia is frequently associated with depression, anxiety, and posttraumatic stress disorder. Other types of chronic pain are also frequently present. The cause of fibromyalgia is unknown; however, it is believed to involve a combination of genetic and environmental factors with half the risk attributed to each.
Central nervous system fatigue
Central nervous system fatigue, or central fatigue, is a form of fatigue that is associated with changes in the synaptic concentration of neurotransmitters within the central nervous system (CNS; including the brain and spinal cord) which affects exercise performance and muscle function and cannot be explained by peripheral factors that affect muscle function. In healthy individuals, central fatigue can occur from prolonged exercise and is associated with neurochemical changes in the brain, primarily involving serotonin (5-HT), noradrenaline, and dopamine. Central fatigue plays an important role in endurance sports and also highlights the importance of proper nutrition in endurance athletes.
