When you are ill, you expect your doctor to tell you what you have, and then to treat you. But sometimes people have symptoms whose cause is not understood and for these people it can be difficult or impossible to get treatment.
The main symptom of Chronic Fatigue Syndrome (CFS) is an overwhelming feeling of tiredness. The tiredness is so disabling that it is impossible for the sufferer to continue normal physical and mental activities. Other symptoms include muscle aches and pains, poor sleep, loss of appetite, a recurrent sore throat, and swollen glands in the neck. Sufferers often undergo many tests for known diseases, which prove negative, and many feel that doctors see them as hypochondriacs.
