There is often no known causes of chronic fatigue syndrome or CFS. Often the patient would be exhausted with joint and muscular pain. And there is no magic pill that magically cure this condition. At most, medication can only be prescribed to manage the symptoms such as painkillers and muscle relaxants for pain and stiffness. I have long suspected that the underlying causes for some cases could stem from a deep unresolved emotional issue that eventually resulted in the person being unable to function as a normal active individual would.
