CL is a 23-year-old woman who experienced intermittent aching around her left eye for several months. It had recently become more constant and was severe enough to wake her from a sound sleep on two occasions. Her primary care doctor had ordered a set of sinus x-rays that were reported as normal. He prescribed pain pills and suggested she consult an eye doctor if her symptoms worsened. She continued to have symptoms and was evaluated by an ophthalmologist who performed a complete eye examination with no objective findings to explain her pain.
