I'm definitely late for an eye exam, yes. Pretty certainly part of it, but it's a thing even when my eye prescription isn't like... two years out of date or something. Mostly cause a eye doc visit + new glasses (or lenses, at least) is rather far from something with no costs, heh. More like at least a hundred USD, possibly two or three depending, far as I can recall from last trip. Definitely less than a brain check, but still kinda' painful. Also some memory junk going on that's been making me regularly forget to do stuff like make an appointment, bleh.
And I'unno SG. I'm fairly sure it's got more to do with some medication I'm on, just getting older, or something along the lines of ADD, if for no other reason than the headache bit's been happening (if to a smaller degree than this last incident) for... probably the better part of a decade. Would think a tumor would have just killed me by now, heh. That particular one was just significantly more intense than it usually is. Less coherent than normal, even for when my head's trying to kill me. Nap's cleared up most of the pain, though I'm also failing a will check and doing the stupid trying to figure out this bloody addon I want to exist, so it may be back soonish.
Do mention it fairly often, but that's mostly because it's been turning me into a fairly inconsistent narrator, such as it is, and I kinda' hate not being clear that some/most of what I'm saying is damnedly likely to be off in some way. It's also personally real goddamn noticeable when three, four years back it was either not happening or notably lesser in impact. Bastard and a half of a thing to regularly be noticing you're having trouble doing shit that was normal just a few years back.
It might not be terribly unusual, though... plenty of people seem to have similar stuff happen without nearly as much distress. Just something I'm pretty sensitive to considering my brain's about all I got worth even a particularly minute damn, these days.
