Cluster headaches have no cure. I think medicine would not hide this information if they knew it.
The disease is complex and purely understood. The symptoms are well known: typically the headache strikes in the middle of sleep, at the onset of REM. It is always one-side of the head, centered on the eyeball from which the pain radiates to the entire half of the head, the teeth, the neck, copious tears, nasal discharge, red skin flushing. The pain is excruciating and lasts on average an hour. Some men have committed suicide rather than go on.
Most sufferers are men; the headaches occur EVERY night for a month or more, then cease and return 12 months later. For some people, such as myself, it is chronic daily, not seasonal. Scientists understand that the malady arises from a malfunction of the hypothalmus, and that the pain is mediated through the trigeminal nerve.
There are approaches to aborting the headache in the first 5 minutes of onset. There are about 6 drugs that can be effective as prophylactics (discovered by trial and error for each person). No cure exists, although LSD shows promise. But LSD is illegal, even for scientists to test.
Per your questions: I meditate, have for decades, but it has no effect for my headaches. The only known trigger is alcohol, which I avoid. We hear that for certain painful conditions, marijuana is a solution. I seldom partake but knew there would be no harm in smoking. So one morning upon waking the headache was there; I went to a friend’s house and we smoked. Ha ha! Now I had a major headache and was high at the same time. I don’t recommend it.
