Painful mile

I woke up this morning with a sore right ankle.  I have no idea where it came from, but it was hard to walk on it all day.  I did manage to get in a mile at the track this afternoon.  Based on my experience, pain that suddenly appears for no reason goes away just as quickly.  So, I am assuming that it will be gone when I get up tomorrow.  This evening, I went to College Station to visit someone at the hospital and then worked out at Iron Works late tonight.
