Chronic migraine. People think its just a headache, but that's really just the most obvious symptom and least complex symptom. Family practice/generalized doctors know too little about it to recognize it. Everyone around you thinks you're just being dramatic. If they can push through a headache then why cant you push through a migraine?
Migraine is a cycle that lasts days. It has phases: prodrome, aura, acute, postdrome. The acute phase (the headache part) is just one phase. Sometimes the headache isn't even that bad, or long. Sometimes it lasts multiple days. Its a neurological disorder and, in a lot of ways, basically is like your nervous system short circuiting for a few hours or days. Triggers have a lot to do with severity, but there is also a lot of bad info about triggers too. With chronic migraine, you could avoid all triggers and still have 1-2 migraine events a month, and those events dont care about your calendar.
Because information is so badly shared and everyone (mostly unintentionally) gaslights anyone with migraine into thinking they're not suffering from a chronic condition, many of us go a long time before discovering useful information or getting diagnosed.
There are a ton of signs during the prodrome phase which, once you know what to look for, can help you avoid (sometimes) the acute phase by taking meds soon enough and focusing on avoiding known triggers. Even standard over-the-counter stuff can short circuit a lot of migraines before the most painful part. But also, some of the prodrome stuff alone can make working or completing tasks difficult. I often start having trouble speaking, get very tired, have difficulty focusing vision. General brain fog. This can be hours or days before an attack.
After the headache phase, the postdrome is often more brain fog, speaking issues, low energy, but also sometimes a euphoric state which can make getting back into your normal schedule really difficult.
I miss family events. I miss friend events. I have to cancel stuff all the time. I worry about scheduling things for fear of being in a headache phase. I've been lucky with employers being understanding, esp with the work from home setup and mostly DIY hours, but i absolutely couldn't work a job with shifts.
