The predominant symptom of cluster headache is the sudden onset of excruciating pain around one eye and forehead and head on same side.

This severe pain may last for few minutes to several hours and usually deteriorate with passing time. The affected individual may sometimes feel very agitated or even violent.
This pain may occur same time each day for several weeks in row and then stop abruptly, to recure again after a few weeks or months. Such episodes of relapse and remission are typical of a cluster headache.
A history eliciting typical pattern of episodic occurrence along with intense unilateral headache is diagnostic of cluster headache. Some imaging modalities like MRI scans or CT scans may be needed to rule out other causes of clinical symptoms before establishing a sure shot diagnosis of cluster headache.
