Troubling Knee Troubles

This past Saturday saw a Pacemaker's run from Panera up on York Rd. down to the Harbor and back up to Panera. 14 miles. As I told one of my running mates, "It was really only the last 12 miles that were painful." My knee has gotten to the point where running is painfully unenjoyable. It is the extension of the right knee, as my foot reaches out for the ground, that causes the pain. I found myself running rather stiff-legged to avoid flexing the knee past 45 degrees. Not ideal by any means. The really odd thing is that it hurts less the fast I go. It also hurts less when I run on a left-to-right camber (think right side of the road). The pain is on the lateral side, just below the patella up to the pivot of the knee. It seems to be lower than most people who experience IT band syndrome, but that doesn't necessarily rule it out. According to the video on this Runner's World page the pain that sits lower than the IT band could be a lateral meniscus tear. However, I haven't had any swelling whatsoever, and from what I have read this is a typical symptom of a meniscal tear.

Taking a week off to see if that helps.
