She doesn't have an extreme case. But I have seen many a lot milder cases than hers (on Facebook, I believe). So it's definitely not a "very mild case". Of course, there are way worse cases, but there are cases that are way, way milder, so she might have a bad case, and people like Daniel, JSL, you, me have very bad cases. You always have to take all the variations into account :)
And yes, we'll have to see if anyone will actually get cured after seeing a lot of progress. It might / will probably take years.
