At 4-ish last night, I noticed that my ear was starting to hurt in that distinctive way, and it was coming on fast.
I woke up about a half-hour ago in pain, and it's already difficult for me to force my jaw closed on that side because it hurts to close the jaw. Touching anywhere near the ear on that side of my face (right side, but it varies each time I get it) hurts. Turning my head hurts. It hurts when it's not disturbed either, but disturbing it hurts it worse.
I grab breakfast and go, before I'm completely incoherent.
