Headache · fatigue · blurred vision · Dx?

One month after moving into her mother's apartment, a 27-year-old woman sought care at our clinic for fatigue, headache, blurred vision, nausea, and morning vomiting. She had weakness and difficulty sleeping, but denied any fever, rashes, neck stiffness, recent travel, trauma, or tobacco or illicit drug use. She did, however, have a 6-year history of migraines.
