Every 6 months or so, my father is afflicted with cluster headaches. He will have an average of three episodes a day, and they last about 15 minutes. This will continue for about 3 months then quit simple. The pain of them are so intense, he’s really asked my mother to kill him in order to stoppen.Hat the pain of anyone out there have any ideas on how to minimize the pain, occur during these episodes? He is on several prescription medications for this disease, but nothing seems to help too much. What works for you?
