Primary stabbing headache (PSH) or ice pick headache is an infrequently studied, yet socially important problem facing children and adolescents. The current study examined the effects of routine external hand warming on the PSH intensity of a 16-year-old male referred for management of recurrent headaches. The participant, Michael, alternated periods of non-warming with periods of daily external hand warming, and an ABAB design was used to evaluate the impact of hand warming on PSH intensity. Results indicate that clinically significant symptom reduction was obtained with implementation of external hand warming.
