Beyond postdural puncture headache: headache and the puerperium

Although postdural puncture headache and headache as a symptom of preeclampsia comprise the majority of "secondary" postpartum headaches, other less-common causes of postpartum headache include headaches caused by cerebral vascular abnormalities, hemorrhagic processes, or mass effects/space-occupying lesions. Many of these less-common headaches herald serious underlying disorders that present a significant threat to patient health and require prompt diagnosis and treatment.
