When there's nothing else on TV, Fiorella watches Mystery Diagnosis to familiarize herself with rare medical conditions, just in case she might someday turn up with one. A recurring pattern is that the patient is initially misdiagnosed, which Fio can identify with. So far she's been misdiagnosed with multiple sclerosis,diabetes (three times), arthritis, histoplasmosis, sleep apnea, and macular degeneration. She's also been suspected of cancer--ovarian, breast, thyroid, and kidney, none of which panned out.
Not to say that she doesn't have some other health problems, but, so far at least, not these.
