Seven years ago I had a bad virus. I've never improved. Many doctors say it's Chronic Fatigue Syndrome. My last dr. said it's viral encephalopathy (brain damage) caused by the virus. Is this true? Carol
It is not currently known what causes Chronic Fatigue syndrome. It is a syndrome that typically starts with flue like symptoms, and involves fatigue that is not significantly relieved by resting.
ME is myalgic encephalomyelitis, and is sometimes known as Chronic Fatigue Syndrome; it appears to be the aftermath of a viral infection. MS is multiple sclerosis, a chronic autoimmune disorder, which causes nerve damage and can affect almost any part of the body. It can cause fatigue.

A viral infection makes you feel unwell by triggering your immune system to respond to the invading virus. This response includes the release of chemicals called cytokines, which can cause inflammation, fever, fatigue, and muscle aches. Additionally, the virus itself can damage cells and tissues, leading to symptoms specific to the infection, such as coughing or gastrointestinal distress. Together, these factors contribute to the overall feeling of malaise associated with viral illnesses.
