What is a Cluster Headache?

Cluster headache is a severe type of headache. It often comes in cycles or “clusters.” People may feel intense pain, usually around one eye. Unlike other headaches, cluster headaches can happen several times a day. Each attack may last from 15 minutes to three hours. Because the pain is so strong, many people find it hard to do daily tasks. According to the World Health Organization, cluster headaches are rare but very disabling. Early recognition can help with better cluster headache treatment.

Common Symptoms of Cluster Headaches

Cluster headache symptoms are unique. They often appear suddenly and without warning. However, knowing the signs can help you seek help sooner. Common symptoms include:

Severe, sharp pain on one side of the head

Pain often focused around or behind one eye

Red or watery eye on the affected side

Stuffy or runny nose on the same side

Swelling or drooping of the eyelid

Restlessness or feeling unable to sit still

Sometimes, people may also notice sweating on the face. The pain can be so strong that it wakes you from sleep. Because these symptoms are intense, it is important to know them well.

Causes and Risk Factors

Doctors do not know the exact cause of cluster headaches. However, experts believe changes in the brain’s hypothalamus may play a role. The hypothalamus controls your body’s clock and sleep patterns. For this reason, cluster headaches often happen at the same time each day. Some risk factors include:

Being male (cluster headaches are more common in men)

Age between 20 and 50 years

Family history of cluster headaches

Smoking or heavy alcohol use

Although triggers like alcohol or strong smells can set off attacks, they do not cause the condition itself. Still, avoiding triggers may help reduce attacks.

How Cluster Headaches Are Diagnosed

Doctors use your symptoms and medical history to diagnose cluster headaches. There is no single test for this condition. However, your doctor may ask about:

When and how often your headaches occur

Where the pain is located

Other symptoms, such as eye redness or nasal stuffiness

Sometimes, doctors may order brain scans like MRI or CT. These tests help rule out other causes of severe headaches. Because cluster headaches are rare, seeing a specialist can help with how to diagnose cluster headache correctly.

Treatment Options for Cluster Headache

Cluster headache treatment aims to reduce pain and prevent future attacks. Your doctor may suggest:

Fast-acting pain relief, such as oxygen therapy or injectable medications

Preventive medicines to lower the number of attacks

Medications like verapamil, steroids, or lithium for long-term control

In rare cases, surgery may be an option if other treatments do not work. Because each person is different, your doctor will choose the best plan for you. Early treatment can help reduce the impact of cluster headaches.

Lifestyle Tips and Prevention

While you cannot always prevent cluster headaches, some lifestyle changes may help. For example, you can:

Avoid known triggers like alcohol or strong smells during a cluster period

Keep a regular sleep schedule

Manage stress with relaxation techniques

Stay hydrated and eat balanced meals

Additionally, keeping a headache diary can help you and your doctor spot patterns. This may lead to better prevention and care. Although cluster headaches are hard to stop, these steps may lower your risk.

When to See a Doctor

If you have sudden, severe headaches, seek medical help right away. Sometimes, headaches can signal a more serious problem. You should also see a doctor if:

Your headaches are frequent or very painful

You notice changes in your vision or speech

You have a fever, stiff neck, or confusion

Because early diagnosis leads to better outcomes, do not wait to get help. Your doctor can guide you on cluster headache symptoms and the best treatment options.
