Headache is a symptom rather than a diagnosis. Pain in the head caused by common primary headaches or an underlying medical or neurological disorder. The pattern, duration, associated symptoms and medical history help a clinician identify the cause.
Why it occurs
Possible causes include Migraine, Tension headache, Sinus or viral illness, Hypertensive emergency or brain disorder. The same symptom can arise from several organ systems, so self-diagnosis can be misleading.
Temporary or chronic?
It may be temporary, recurrent or persistent depending on the underlying cause.
Why timely care matters
It may be dangerous when sudden, severe, progressive or associated with emergency warning signs.
