On a different note but still about subjective mental stuff, I don't know if I get migraines or not. I assume I just get bad regular headaches but every time I google it, it's hard to tell how other people's descriptions compare to mine.I've had a similar thing.
I luckily haven't had a major one in maybe a decade since I learned to take tylenol and rest when the symptoms first start. As a kid it'd be debilitating pulsing pain originating at the back/top of the neck and strong sensitivity to lights, but none of the other migraine things like nausea that I can remember.
Except I have had vomiting with my headaches.
But a lot of websites talk about migraine aura, so similarly I wasn't sure if I was actually having a migraine because of that.
But I realized later that I have had migraine aura, just not frequent.
