Chronic Fatigue Syndrome (CFS) is a lifelong condition characterised by fatigue that interferes with a person’s daily activities. In this case, the fatigue does not go away with rest or a whole night’s sleep.
Symptoms of CFS include fatigue for at least six months that is not curable with bed rest, frequent headaches, chronic insomnia (inability to fall asleep), tender lymph nodes on the armpits and neck and joint paint without redness or swelling.
