- [What Is Cluster Headache? Symptoms, Types, and Diagnosis](https://clusterbusters.org/what-is-a-cluster-headache/): If you have never had a cluster headache, it is hard to describe what one feels like\. An icepick driven behind the eye\. A hot poker\. A brain freeze that lasts an hour instead of a few seconds\.
