Right - just not in the first several posts until after people had answered - not criticizing, just making the point of why we need to see our own docs and not just come here for advice instead. Among other reasons, even qualified physicians can't examine you online and don't have the whole story. Hence why Dr. Edwards would have thought it looked only like immunity from past infection - you didn't mention symptoms in the first post.
Again not targeted at you, just pointing out how we as ME patients need to do a good job of putting questions in context.
