Can cluster headaches cause other serious health problems?
• Cluster headaches are usually not the cause of other serious health problems. You may have side effects from certain medications used to treat your cluster headaches. Because of the severe pain they cause, cluster headaches may decrease the quality of your life. Some people have anxiety (worry) or depression (sadness) because of their pain. People who have frequent cluster headaches may sometimes have thoughts of ending their life. If you have thoughts of hurting yourself, tell a caregiver right away. • Some people who have cluster headaches are at an increased risk of getting permanent Horner syndrome. Horner syndrome is having a droopy eyelid or small pupil in one eye. These symptoms may happen during a cluster headache, but usually go away when the headache stops. Over time these symptoms may stay, even between headaches. For support or more information: Some people find it helpful to talk with others who are also living with cluster headaches.
