While I'm not a doctor, that doesn't sound like a cluster migraine.I was diagnosed with cluster migraines, but I don't think that was correct. They were just regular migraines, but they were somewhat consistent, like 1-3x a month, somewhat seasonal (I could go a couple months without one).
Cluster headaches are very different than a standard migraine in that they don't last as long - between 20 minutes to 4 hours each, and you get 2+ a day, every day, around the same time of day, for several months, around the same time of year. Mine started between January and March and I got 4 headaches every day for about 3 - 4 months. Some poor fuckers get them chronically, meaning they don't go away after a few months, they just keep getting them, every day for a year or more. Most of the chronic people end up killing themselves which is where the nickname, 'suicide headache' comes from.
Clusters also only effect 1 side of your body - brain, head, neck, shoulder, breast and with some people, also their back. For me, it is the left side. I could tell when I was about to get one when my left eye began to water, or my left sinus would begin to clog, or if I began to lose my hearing in my left ear. If I didn't inject myself right away and bring out the oxygen tanks, I was fucked in 10 minutes. That is if the injection and the oxygen worked which the odds were never in my favor.
I know we are all getting older so taking psychedelics is not on the menu but if you are suffering from migraines, I would definitely look into 'Busting'. Now I don't know if busting will work with standard migraines or not but it's worth looking into. Fuck living with this kind of pain.
