Cluster Headaches

Cluster headaches are short, brutal attacks of one-sided head pain that strike in cycles. They are one of the most painful conditions we treat, and most patients have been searching for relief for years.

Overview

A cluster headache is a sudden, severe, stabbing pain around or behind one eye. Attacks last 15 minutes to three hours and often come with a watery eye, runny nose, or drooping eyelid on the same side.

Cluster headaches happen in bouts, sometimes several a day, for weeks or months at a time. Between bouts, patients can be completely pain free. Targeted interventional care can cut attack frequency and shorten the cluster period.

Symptoms & causes

Cluster headaches are distinct from migraines. If your attacks feel sudden, one-sided, and come in predictable cycles, this may be the diagnosis.

Severe, stabbing pain around or behind one eye
Attacks lasting 15 minutes to three hours, often at the same time of day
Watery eye, runny nose, or droopy eyelid on the affected side
Restlessness or pacing during an attack

When to see a doctor

Seek care if…

Seek emergency care if you have the worst headache of your life, vision loss, weakness, confusion, slurred speech, or a headache after a head injury. These can point to a more serious problem.

Frequently asked questions

How is a cluster headache different from a migraine?

Cluster headaches are shorter, more intense, and always on one side. They come in bouts with pain-free gaps, often at the same time of day. Migraines are longer, come with nausea and light sensitivity, and rarely include the tearing eye or runny nose seen in cluster.

How fast does the SPG block work for cluster?

Many patients feel relief within minutes of the procedure. The benefit can last days to weeks, and we often repeat the block during active cluster periods.

Can these attacks ever stop for good?

Cluster headaches tend to come and go over a lifetime, but treatment can shorten cycles dramatically and reduce attacks within a cycle. Some patients go years between bouts with the right plan.
