A few months ago I got into a rather lengthy discussion with Jurassic Referee regarding what exactly constituted a "foot" on the court.  I just re-read that thread and had to chuckle.  
 
Ironically, a few of the 26 bones, 33 joints, 19 muscles and 107 ligaments that form my left foot ARE KILLING ME! 
 
  
 
 
Specifically, I am suffering from Plantar Fasciitis.  Anyone have some advice on dealing with this.  It doesn't hurt much while I'm running on the court, but HOLY COW within a couple of hours after I stop running GAWD IT HURTS.  The first few steps in the morning almost bring me to tears.
