The headache usually lasts 30 to 60 minutes but can last up to 3 hours. 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 male. They often begin when the person is between the ages of 20 and 40 years. If you smoke or have a family history of cluster headaches, you are more likely to get them.

What are the signs and symptoms of a cluster headache? 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. You may also have any of the following:

• Severe pain on one side of your head that stabs or burns

How is a cluster headache diagnosed? Your healthcare provider will ask you to describe your symptoms. Tell him how often your headaches occur and how long they last. He will ask about your medical history. He will look at your face and eyes. He will ask for a list of your medications. Tell him if you smoke cigarettes or drink alcohol. You may 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. He may ask questions to check your memory. He may check your 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 your body.

How is a cluster headache treated? There is no cure, but treatment may help your signs and symptoms. Your healthcare provider may have you try several medicines to find out what works best for you. You may need a blend of 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.

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.

How can I manage my cluster headaches?

Do this to learn what triggers your headaches and how to make them go away.
