Chronic Fatigue Syndrome, also known as CFS or CFIDS (Chronic Fatigue Immune Dysfunction Syndrome) is an illness characterized by prolonged, debilitating fatigue and multipe symptoms such as headaches, recurrent sore throats, muscle and joint pain, and cognitive problems. The illness is poorly understood and difficult to diagnose. Diagnosis is made by excluding diagnoses for other diseases with similar symptoms and also by the patient's symptoms meeting the criteria for CFS as defined by CDC (Centers for Disease Control). The profound fatigue associated with CFS is a hallmark of the illness, and is far more than normal tiredness.Fibromyalgia is a common and disabling disorder affecting 2-4% of the population, women more often than men. Despite the condition's frequency, the diagnosis is often missed. Patients with fibromyalgia usually ache all over, sleep poorly, are stiff on waking, and are tired all day. They are prone to headaches, memory and concentration problems, dizziness, numbness and tingling, itching, fluid retention, crampy abdominal or pelvic pain and diarrhea, and several other symptoms.
Most researchers believe CFS and fibromyalgia are related syndromes, if not the same. Many of the symptoms do overlap. Most CFS patients also have fibromyalgia symptoms. If you are interested in more information, please explore the links I have provided on this page.
