Primary stabbing headache in adults and pediatrics: a review.

Primary stabbing headache (PSH) is an under-recognized primary headache disorder, which often goes undiagnosed. It is mainly characterized by its ultrashort stabbing quality and can be easily overlooked both by patients and providers as it is often not severe enough to interfere significantly with daily life. However, PSH may be severe and require therapy, and it is important for providers to recognize this headache type, both in adult and pediatric populations, as well as to be able to distinguish it from secondary headache disorders. PSH also may be more common than previously thought.
