Uh-oh - painful heel injury

My right foot hurt all day today, from when I got up, to right now as I'm typing this at almost 9 PM. The pain starts in the heel, actually near the achilles tendon, and runs forward under my heel to the arch.

And, now that I think about it, it hurt right when I started running yesterday. I had to cross SE 17th, which is a busy street, during rush hour, and I took off quickly and came down a bit hard on the heel. But once I got moving, as I reported yesterday, it warmed up and felt fine.

Not so today, however. I kept stretching it when I could, but my morning was spent in a boring project management presentation, so I had to sit there for four hours straight. That might sound good for a painful foot, but actually I'd rather be moving around, flexing the foot, putting weight on it, and warming it up. However, sadly, no.

I'm icing it now, and once I'm done with the icing I'm going to put it in a tub of warm water and Epsom salts, and then maybe some icing again and then warm water and Epsom salts. I have got to be 100% for the race this weekend, and, y'know, for the rest of the year.

Not that I'm obsessed or anything.
