Seeing the doctor

I have an appointment tomorrow to see my doctor about the pain in my left leg.  It started hurting quite bad last week, and didn't let up over the weekend.  I have been unable to even think about running, and haven't had the time to ride my bike.  It looks like I got a mandatory week break from training.  It is 31 days till The World's Toughest.  I figure that I am in good enough shape right now, but I couldn't do it with my leg the way it is.  We will see how things go.
