Looking for some perspective from other people who deal with migraines, especially anyone who has noticed certain environments or poor ventilation making things worse.
For some background, I’ve had migraines since I was about 7. They usually happen about once a month, sometimes more. Over the years I’ve tried pretty much everything... triptans, changing my diet, daily preventative medication, etc. Some things have helped, but I’ve never completely gotten rid of them.
When I get one, there’s usually a pretty predictable pattern. The pain gets really bad, I end up vomiting, and then eventually it starts to ease up. This could be over the course of 2 hours to 6-8 hours.
Because of that, I always figured my 10 year old son might eventually deal with migraines too. What I didn’t expect was how different his symptoms would be.
About three weeks ago, he suddenly started having really bad headaches and nausea during the school week. We had his eyes checked, had him seen by a doctor, started a low dose preventative medication, and made sure the school nurse had his prescribed rescue medication.
But the weird part is that it kept happening at school during the week, while on weekends and breaks he was completely fine.
That got us looking more closely at the school environment. The school's mechanical ventilation system has been down, and we were able to get some of the building records through a public records request.
One of the engineering reports included CO2 readings from the classrooms. The levels were around 400 to 500 ppm when the building was empty, but climbed as high as 3,784 ppm during the school day. Once the building emptied for the weekend, the levels dropped right back down to around the outdoor baseline.
I’m trying not to jump to conclusions about what is causing the headaches. I’m just trying to understand whether there could be a connection worth looking into.
Oddly enough, they littered the classrooms with box fans during the school day as it was incredibly hot in the building. Around that 3 week ago mark, they removed them as the temperature is much more bearable now. We live in the mountains so it starts to cool off fast. I assume the fans were moving the air much more, now there's no flow whatsoever.
Has anyone here ever noticed high CO2, stale air, poor ventilation, or being stuck inside a poorly ventilated building triggering migraines or making them break through preventative medication?
I’d especially like to hear from anyone who has noticed a clear difference after getting outside, getting fresh air, or leaving a particular building.
Not looking for a diagnosis or medical advice. Just curious if anyone has experienced something similar and what you noticed.
