well this is unsettling as fuck

[wandering_lemma]

My left eyeball has been throbbing all day. Advil has not affected it. Every two minutes or so it feels like somebody is grabbing it and squeezing it. It doesn't hurt cause it's the eyeball and not, say, the optic nerve, but um...creepy. Is this one of those things, that when someone is plotting your death, you feel it in your eyeball? Kind of like a "by the pricking of my thumbs" thing?
