They hit like a drill behind one eye. They come in bursts — repeated short attacks over days or weeks — then disappear. If you wake up with a severe stabbing pain on one side and your eye waters or your nose runs, think cluster. These headaches are different from migraine: they are shorter (15–180 minutes), intensely sharp, and often occur at the same time each day.
Common signs include sudden one-sided pain, restlessness or pacing during an attack, red or teary eye, nasal congestion on the same side, drooping eyelid, and sweating. Attacks can happen multiple times per day, sometimes waking people from sleep. Because attacks are brief but brutal, people often describe them as the worst pain they have felt.
If you're mid-attack, two treatments work best fast: high-flow oxygen and injectable triptans. Inhaling 100% oxygen at 12–15 liters per minute for 15 minutes often stops an attack quickly for many people. Sumatriptan injections (subcutaneous) act fast too; oral pills are usually too slow. Nasal triptans or zolmitriptan nasal spray can help if injections aren't an option. Avoid taking opioids — they don't work well and can make things worse.
Short-term preventive drugs can reduce attack frequency while longer-term prevention takes effect. Transitional options include a short steroid taper or occipital nerve blocks given by a physician. These are used to break a cluster phase quickly while other preventives kick in.
Verapamil is the most common daily preventive drug for cluster headaches. It can significantly cut or stop attacks in many people but requires ECG monitoring because it can change heart rhythm. Lithium is another option for chronic cluster headaches; it needs blood tests and close follow-up. Topiramate, melatonin, and gabapentin sometimes help, but results vary.
Lifestyle changes support treatment: avoid alcohol during a cluster period, keep a regular sleep schedule, and track attacks in a diary or app to spot patterns. If smoking, try to quit — smoking is linked to higher cluster risk. Know your triggers (alcohol, strong smells, nitrites) and steer clear during active phases.
See a neurologist if attacks are new, happen several times per day, or don't respond to oxygen or triptans. Seek urgent care if pain is unlike prior attacks, accompanied by fever, vision loss, or weakness — these signs need immediate evaluation. A specialist can confirm the diagnosis, order imaging if needed, and set up a prevention plan.
Tracking attack timing, duration, and triggers helps your doctor tailor treatment. Carry a fast-relief plan (oxygen prescription or a triptan) and a prevention plan for cluster seasons. With prompt treatment and tracking, many people reduce attack severity and regain daily function.
Keep an emergency checklist: oxygen tubing, mask, fast-acting triptan, emergency contacts, and your headache diary. If you travel, confirm oxygen supplier and local ERs. Regular follow-up with your specialist lets you adjust meds safely and stop a cluster phase sooner. Talk openly with your care team.
As someone who's experienced cluster headaches, I wanted to share some information about Verapamil, a treatment option that has been quite helpful. Verapamil is a calcium channel blocker that works by relaxing blood vessels, thus easing the pain of cluster headaches. It's typically prescribed as a preventive medication to be taken daily, reducing both the frequency and severity of attacks. Before using Verapamil, it's essential to consult with your doctor for proper dosage and potential side effects. In my experience, it has greatly improved my quality of life and I hope this information can help others suffering from cluster headaches as well.
