Mine has been going on for 5 weeks or so and some mornings I need to hop on one foot. Iwas hoping that one day it'd go away like yours did, Sumo.
In the last doubles I hit a crappy FH and I anticipated a short volley from opponent by slowly moving up. But he volleyed the ball deep behind me and I did a 360 turn on the injured foot to retrieve the shot.. Wow what a pain! It was like I walked on hot coal.
