A cluster headache strikes quickly, usually without warning, although you might first have migraine-like nausea and aura. Common signs and symptoms during a headache include: 
Excruciating pain that is generally situated in, behind or around one eye, but may radiate to other areas of your face, head and neck
One-sided pain
Restlessness
Excessive tearing
Redness of your eye on the affected side
Stuffy or runny nose on the affected side
Forehead or facial sweating on the affected side
Pale skin (pallor) or flushing on your face
Swelling around your eye on the affected side
Drooping eyelid on the affected side
 People with cluster headache, unlike those with migraine, are likely to pace or sit and rock back and forth. Some migraine-like symptoms — including sensitivity to light and sound — can occur with a cluster headache, though usually on one side. Cluster period characteristics A cluster period generally lasts for several weeks to months. The starting date and the duration of each cluster period might be consistent from period to period. For example, cluster periods can occur seasonally, such as every spring or every fall. Most people have episodic cluster headaches. In episodic cluster headaches, the headaches occur for one week to a year, followed by a pain-free remission period lasting 3 months or longer before another cluster headache develops. Chronic cluster periods might continue for more than a year, or pain-free periods might last less than one month. During a cluster period: 
Headaches usually occur every day, sometimes several times a day
A single attack can last from 15 minutes to three hours
The attacks often occur at the same time each day
Most attacks occur at night, usually 1 to 2 hours after you go to bed
 The pain usually ends as suddenly as it began, with rapidly decreasing intensity. After attacks, most people are pain-free but exhausted.
