End of Riding?

I did a roughly 16 mile shed ride with friends today and alarmingly, in the last quarter the familiar knee pain came back! A quick research on the internet I found this wikipedia entry:

Symptoms

Iliotibial Band Syndrome symptoms range from a stinging sensation just above the knee joint (on the outside of the knee or along the entire length of the iliotibial band) to swelling or thickening of the tissue at the point where the band moves over the femur. The pain may not occur immediately during activity, but may intensify over time, especially as the foot strikes the ground. Pain might persist after activity. Pain may also be present below the knee, where the ITB actually attaches to the tibia.

Yes, those are the symptoms I'm suffering right now. The wiki then says:

Sports activities to avoid while symptomatic:
...
Cycling

Uh, that doesn't sound good. And it goes on:

Causes

Iliotibial Band Syndrome is the result of poor training habits, equipment and anatomical abnormalities.

Training habits:

...
* In cycling, having the feet "toed-in" to an excessive angle

um, that could very well be the reason. I'll try to change the cleats position a little and pay attention not to toe in too much.

Anyway I hope this is not the end of riding.

BTW, Both Rob (last time) and Dan (today) mentioned to me it could be the Iliotibial Band Syndrome. I believe they were right.
