TIL about [cluster headache](https://en.wikipedia.org/wiki/Cluster_headache)

> _“The #pain […] is usually described as burning, stabbing, drilling or squeezing. While #suicide is rare, those with cluster headaches may experience suicidal thoughts (giving the alternative name ‘suicide headache’ or ‘suicidal headache’). […] The disease may be the most painful condition known to medical science. […] #ClusterHeadache is probably the worst pain that humans experience. […] Women with cluster headache will tell you that an attack is worse than giving birth. So you can imagine that these people give birth without anesthetic once or twice a day, for six, eight, or ten weeks at a time. […] Their pain was so severe that several of them had to be constantly watched for fear of suicide. Most of them were willing to submit to any operation which might bring relief.”_
