WHAT YOU NEED TO KNOW:
What is a cluster headache?
A cluster headache is a very painful headache that starts quickly, peaks within 15 minutes, and stops suddenly. The headache usually lasts 30 to 60 minutes but can last up to 3 hours. Cluster headaches follow patterns and often occur at the same time of the day or year. You may have cluster headaches once every other day, or up to 8 each day. A cluster period usually lasts for 2 to 12 weeks but can last longer than a year. Weeks or months may pass before a new cluster period begins. A cluster headache can be triggered by alcohol, medicine, stress, bright light, or heat.
What increases my risk for a cluster headache?
The cause is not known. You are more likely to have cluster headaches if you are a man. They often begin between the ages of 20 and 40 years. Your risk is also higher if you smoke or have a family history of cluster headaches.
What are the signs and symptoms of a cluster headache?
- Severe pain on one side of your head that stabs or burns
- Swollen or watery eye, or droopy eyelid
- A runny or stuffy nose
- Red or sweaty face
- Sensitive to noise or light
- Exhaustion after the headache stops
How is a cluster headache diagnosed?
Your healthcare provider will ask you to describe your symptoms. Tell the provider how often your headaches occur and how long they last. The provider will ask about your medical history and medicines. Tell your provider if you smoke cigarettes or drink alcohol. You may also need any of the following tests:
- A neurological exam is a series of tests to check for problems with your brain and nervous system. Your healthcare provider will shine a light in your eyes to find out how they react to light. The provider may ask questions to check your memory, hand grasp, and balance.
- CT scan or MRI pictures may be taken of your brain and the blood vessels and structures in your head. You may be given contrast liquid to help images show up better on the monitor. Tell healthcare providers if you have ever had an allergic reaction to contrast liquid. Do not enter the MRI room with any metal. Metal can cause serious injury. Tell the healthcare provider if you have any metal in or on your body.
How is a cluster headache treated?
Cluster headaches cannot be cured, but treatment may help your symptoms. Your healthcare provider may have you try several medicines to find out what works best for you. You may need medicines for pain and for prevention. The following may be used to treat pain during a cluster headache:
- Extra oxygen may give you pain relief during a cluster headache. You will breathe through a plastic mask that is attached to an oxygen tank for about 15 minutes.
- Migraine medicine may be given to relieve your pain quickly.
- Steroids may help reduce pain and swelling. Steroids may also be used to prevent cluster headaches.
- Numbing medicine may be given to numb your pain if other treatments do not work.
- Surgery may be used if other treatments do not work. Surgery may be used to remove certain nerves that can lead to cluster headache pain. You may also need surgery to lower pain and inflammation in the nerves around your eye.
What can I do to prevent a cluster headache?
One goal is to prevent headaches before they happen. Another goal is to shorten a cluster period. Headaches may happen less often and be less severe with certain medicines. Seizure medicine or mood stabilizers may be given to prevent cluster headaches. You may need to take one medicine at the start of a cluster period. You may take a different medicine for as long as your cluster period lasts or is expected to last.
What can I do to manage cluster headaches?
- Do not smoke. Cluster headaches are more common among smokers. Ask your healthcare provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your healthcare provider before you use these products.
- Do not drink alcohol during a cluster period. Alcohol triggers more headaches during cluster periods.
- Do not travel between altitudes. Altitude changes can trigger headaches. Do not fly on an airplane or travel between places with high and low altitudes.
- Set a regular sleep schedule. Go to sleep and wake up at the same times each day. Changes in sleep patterns may trigger cluster headaches.
- Manage stress. Stress, long hours at work, and emotional challenges can trigger cluster headaches. Find out what works for you to lower stress.
- Keep a headache record. Write down when your headaches start and stop, and exactly what you were doing when they began. Record what you ate or drank and how much you slept in the 24 hours before the headache. Keep track of the things you did to treat your symptoms. Write down if they did or did not help. Do this to learn what triggers your headaches and how to make them go away.
- Work with your healthcare provider to manage your pain. Both pain relievers and medicines used to treat other health conditions can trigger cluster headaches. Go over all your medicines with your healthcare provider. Work with your provider to manage your headache pain and other conditions.
