I originally posted this on reddit, and someone pointed me in this direction, and I'm finding clusterbusters to be a wonderful resource and community so far. Thank you all!
I'm sharing my story for reactions, I'm trying to connect some dots.
tl;dr it seems very interesting that I developed what I believe to be cluster headache attacks just weeks after giving up caffeine cold turkey after fairly regular consumption for decades.
Longer version: I've been dealing with migraines for my entire adult life, about 20 years. Most of the time the migraines were episodic and managed with basic treatment: rest, ice, typical OTC meds (including excedrin).
I have had periods where the migraine frequency increased, but nothing like fall 2023. Suddenly I was having migraines daily, the light sensitivity really took over, started wearing FL-41 glasses nearly full-time.
I quickly got my act together and got an alternative acute medicine, Sumatriptan, which works well for me. I tried to power though while paying attention to my excedrin and Sumatriptan usage. That strategy wasn't working as well as I'd like, so on December 24th I decided to quit excedrin cold turkey. I also quit caffeine more broadly, which mainly meant no more daily soda. I was hoping that caffeine addiction and/or excedrin overuse was triggering my migraine frequency.
I knew quitting cold turkey would be brutal, but I had around 3 weeks off for the holidays, and I wanted to maximize my chances at normalizing before returning to work. As expected, the withdrawal headaches were brutal. The first few days were rather painful, though they matched the pain severity and location from bad migraines I'd had before. Then on the 4th day, December 28th I got a very different kind of headache.
Normally my migraines are one-sided, sometimes more centered around the forward 1/3 of my head (what many would describe as a tension headache), but this new headache was very localized. It felt like a knife was slicing down my forehead and into my right eyeball. The severity on that first day wasn't horrific, it was similar to a bad migraine, just a different pain pattern. I didn't think much of it at the time, I figured it was just a weird withdrawal headache.
Welp, I was wrong. Since then I've had 4 more of these headaches, but the pain severity went from modest to severe in a few minutes. Each time it lasts about 10 - 20 minutes. I thought I understood pain before, I was wrong. Holey moley these things hurt. This initiated a lot of research and has led me to believe I am experiencing cluster headaches (severity and location of pain, eye watering/sobbing, congestion, desire to move around, etc). The only thing that's off, is the frequency. I've had 3 of these thing over an 8 week period. It seems like most folks have these daily for a time period (hence the cluster name), but it's not always the case.
Also, I discussed this with my mom, and she confirmed that she and my grandma have both episodic migraines and cluster headaches. She hasn't mentioned it before, but they developed them earlier in life, and they matched the common pattern of a brutal short headache every day for a while, then suddenly nothing for a year, then bam it's back.
In any case, I find it peculiar that these suddenly started at age 37 after decades of migraines, just weeks after quitting caffeine. Perhaps the regular caffeine usage was mitigating them before?
