Postpartum Headaches:

• Occurs in up to 40% of woman during the first week after delivery.
• Though thoughts of Sheehan's syndrome (pituitary infarction), and SAH might come to mind the most common causes are due to migranes and tension headcaches.
• About 5% are spinal  (postdural) headaches due to a persistant CSF leak from spinal anesthesia or a complication of their epidural catheters.
• Rare causes include embolic stroke, carotid and vertebral artery dissections, SAH, Central Venous Sinus Thrombosis and Sheehan syndrome.

• Most headaches can be treated the same as any other person.
• Make sure you inquire about breast feeding and ensure the medications you are giving will not be excreted into the breast milk. 
• If your patient has signs of hypopituitarism an MRI scan will be needed to make the diagnosis of Sheehan syndrome.
