There Is An Associated Stuffy Nose, Tearing Of The Eyes, And Drooping Eyelids With Cluster Headaches

Cluster Headaches is a type of primary headache disorder characterized by recurring episodes of severe pain on one side of the head, usually around or behind the eye. These headaches occur in clusters, hence the name, with each cluster lasting anywhere from a few weeks to several months. The headaches are often described as excruciating and have been referred to as "suicide headaches" due to the intense pain they cause.
