Do doctors believe in a post viral syndrome? or believe viral illness can be the cause of other issues whether mental or physical example. would it make sense to treat symptoms and monitor patients until they recover?

Post Viral Syndrome: Post viral syndrome is well documented but poorly understood. The symptoms can include severe fatigue, joint/muscle pain and confusion/forgetfulness. Symptomatic treatment with OTC pain relievers, stretching exercises, rest and increased fluids/electrolytes are the best protocol as they avoid the complications that can be caused by narcotic pain relievers, antidepressants or immunomodulators.
