Aaaargh! I'm getting that stupid knee pain in my good knee.

It started yesterday, about 1 1/2 hrs into my ride. I'm keeping my cadence 85-90 and am staying in the middle chainwheel on the flats. It's on the lateral side of my left knee. I have raised my seat yet some more and it's still bugging me on the rides. With each ride, it's getting worse. Dang it! I was sidelined with this same problem and I blamed it on my other bike being too small. I guess it's iliotibial band? I have Specialized mtb shoes, Speedplay Frogs, and now this. Argh!

Would adjusting the cleat help? Or do I need to head to the ortho doc already?

I don't have any tears (at least it didn't show up in the MRI last year) in the meniscus.
