I was diagnosed with CFS 20 years ago. Three months ago, I started having neurological symptoms, like slurred speech, weakness and clumsiness. Now I have a diagnosis of multiple sclerosis. My neurologist, an MS specialist, thinks I may have had MS all along. I told him, "In 1987 I had a bad case of the flu, and I felt sick every day for FOUR YEARS before I had ONE 'normal' day. You think that could be MS?" He said, "Yes. A viral illness can trigger an MS experience like that." It seems totally implausible to me - but it got me wondering, is CFS an unusual manifestation of MS?
