Chronic Fatigue Syndrome


Chronic fatigue syndrome means that you feel so tired that you can no longer do your normal daily activities. There are other symptoms too, but being very tired for at least 6 months is the main one. Many people improve in a year or two. Some people continue to have severe fatigue and other symptoms for many years.
