I was supposed to test my knee on Saturday. I didn't. It didn't feel right. I did go for a run Sunday, however, 10 days after my last run.

Twenty-seven minutes after I popped out the front door, I came back in through the garage. "How'd it go?" my wife asked.

"Not good."

A planned four-miler became three and a half, as my knee stiffened throughout. Never got sore, necessarily. But it didn't feel great, either. The rest of the day - and right now, I wince at 12:30 p.m. Monday - it got sore if it stayed flexed in one position for any period of time.

So now I'm back to the orthopedist this afternoon. We'll see what happens...
