Chronic fatigue symptoms
Many of the chronic fatigue symptoms are similar to that of flu (muscle aches, headache and fatigue). The unexplained fatigue is present all the time and the can no longer maintain its previous levels of functioning at work and in social live.
The primary symptoms of chronic fatigue syndrome refer to:
- new onset fatigue or tiredness that lasts for at least 6 months and is not relieved by normal rest;
- full-body fatigue serious enough to restrict normal activity.
The additional symptoms include:
- constant headaches, different those previous in pattern, quality, or severity;
- feeling unrefreshed after normally adequate sleep;
- forgetfulness, cognitive impairment including confusion or difficulty concentrating, or irritability
- joint pain, often moving from joint to joint (migratory arthralgias), without joint swelling or redness;
- low-grade fever (101F or less);
- lymph node tenderness and swelling in the neck or armpit;
- muscle aches (myalgias);
- muscle weakness, all over or multiple locations, not explained by any known disorder
- sore throat, red but without drainage or pus.
CFS symptoms either hang on or come and go frequently and some patients also report problems like: nausea, irritable bowel syndrome, bloating, chronic cough, diarrhea, dry eyes, irregular heartbeat, chest pain, jaw pain, night sweats, alcohol and drug intolerance, dizzy spells, tingling sensations and lack of appetite. |
