Snapshot
  • A 36-year-old female has been visiting her primary care physician very frequently over the past seven months because she is afraid she has an underlying illness. She has been experiencing mild, nonspecific abdominal pain off and on throughout this time. Despite reasssurances by her doctor, as well as a normal abdominal ultrasound and abdominal CT scan, she is still convinced something is being missed. Because of her fear, she has become socially withdrawn and spends much of her time at home researching diseases on the internet.  (Illness anxiety disorder)
