Woke up this morning and the top of my left foot felt sore. I can't think of any time yesterday when I might have twisted my ankle, but it feels like that sort of soreness. The last time my foot started hurting like that out of the blue, it got worse over a period of days until I had to go to the hospital, and turned out to be reactive arthritis. I really, really hope it's not that again. Despite working at a hospital, I don't have health insurance currently, so I'd have to pay out of pocket for any treatment.
