What is the typical duration of a cluster headache episode?

A cluster headache episode typically lasts between 30 to 45 minutes, making this the correct answer. Cluster headaches are known for their sudden onset and excruciating pain, which is often focused around one eye or one side of the head. The pain reaches its peak quickly and tends to resolve within this timeframe.

While cluster headaches may be recurrent throughout the day or occur in clusters over weeks or months, the individual attacks are distinct in their duration. Other options suggest durations either too short, like less than 10 minutes, or too long, such as several days, which do not align with the established characteristics of cluster headache attacks. The 1-2 hours duration can occur but is less typical when looking at the most common presentations of these severe headaches.
