Chronic fatigue syndrome (CFS) is a disorder characterized by persistent and unexplained fatigue resulting in severe impairment in daily func-tioning.
Fatigue lasts for at least 6 months.
Fatigue results in a substantial reduction in previous occupational, educational, social, and personal activities.
Four or more of the following symptoms are concurrently present for 6 months: impaired memory or concentration, sore throat, tender cervical or axillary lymph nodes, muscle pain, pain in several joints, new headaches, unrefreshing sleep, or malaise after exertion
Next Steps
I think we should exclude other causes of fatigue before reaching chronic fatigue syndrome
complete blood count; erythrocyte sedimentation rate; C-reactive protein; serum
creatinine,
electrolytes, blood glucose;
liver function tests;
thyroid-stimulating hormone; and urinalysis.
I think u should get these tests done ...
if already done kindly send me reports and let me analyse
hope the information is useful
