Chronic fatigue syndrome (CFS) is an illness characterised by prolonged, debilitating fatigue and several other symptoms including substantial impairment in short term memory or concentration, tender lymph nodes, muscle pain, multi joint pain without swelling or redness, headaches of a new type, pattern or severity, and unrefreshing sleep. A university study indicates that employees who work in office administration are two times as likely to suffer from CFS in comparison to employees in the manufacturing industries. Treatment programs are directed at relief of symptoms, with the goal of the patient regaining some level of pre-existing function and well-being. The reasons behind CFS onset, despite two decades of research, remain unknown and patients are often misdiagnosed as depressed or just plain lazy. CFS patients have a long and enduring battle ahead of them as symptoms usually last a minimum of two years.
