I can’t write much. Earlier this evening I felt the onset of a what I think is a cluster headache, and by now it has reached full force. Unlike migraines, there seems to be little one can do to avert them. At least, I haven’t found the silver bullet. Worse still, I don’t really know what the trigger is. And I fully understand how people can go insane from such headaches. No matter what I do, the only small relieve comes from holding my head tightly. Even that wears off after a minute or two, and the pain is shooting through my head again. All the time I’m thinking that if I just cool my head, or warm it up a little, turn this way or that, it will get better, but every attempt draws a blank. I try to take my mind off the pain, but it doesn’t really work, and pain medication has no effect. I think I have to go outside now to cool down a little.
