[What do I need to know about headaches if I am a Primary Care doctor?].

Headache is among the most invalidating diseases for daily life activities and the most frequent consultation in Primary Care (PC). In spite of this, recent studies have shown that more training is necessary in PC, both in the diagnosis and treatment of headache patients. Our aim is to review, from a practical clinical view, the management of headache in PC, as well as to mention the new options for the treatment of patients with refractory primary headaches. With that objective, we revise the red flags for the diagnosis of serious secondary headache, the tricks for the diagnosis and initial treatment of primary headache, focusing in migraine, the headache which accounts for more than two-thirds of consultations due to headache in PC.
