Flu-Like Symptoms
People with chronic fatigue syndrome might have many flu-like symptoms, which last for days and recur frequently. Since these health issues are not uncommon, they are not needed for a diagnosis. Typical flu-like symptoms include digestive issues, nausea, chronic cough, tender lymph nodes, sore throat, low body temperature, low-grade fever, night sweats, excessive sweating, or chills. [7]
