4.5.1 Headache attributed to external application of a cold stimulus

An 11-year-old girl has had four short-lived headaches this summer, each one starting only when she was eating an ice lolly or crushed ice too quickly. Her mother reports that the pattern always begins while the cold treat is actually in her mouth or against the roof of her mouth, and never at any other time. As soon as she stops eating and the cold sensation passes, the headache eases off, and each episode has been fully gone within about ten minutes of her putting the ice lolly down. She describes it as a brief, sharp pain across her forehead, without any crying spells suggesting more severe pain, nausea, or visual change. She is otherwise a well child with no significant medical history.
