Article Excerpts About Symptoms of Chronic Fatigue Syndrome:

For many people, CFS begins after a bout with a cold, bronchitis, hepatitis, or an intestinal bug. For some, it follows a bout of infectious mononucleosis, or mono, which temporarily saps the energy of many teenagers and young adults. Often, people say that their illnesses started during a period of high stress. In others, CFS develops more gradually, with no clear illness or other event starting it.

Unlike flu symptoms, which usually go away in a few days or weeks, CFS symptoms either hang on or come and go frequently for more than six months. CFS symptoms include:

  • Headache
  • Tender lymph nodes
  • Fatigue and weakness
  • Muscle and joint aches
  • Inability to concentrate
