Comment from yesterday's blog

Ok, I really should have waited to post that blog last night. I really truly fell asleep in the middle of writing it. I just noticed that I said I had clicking at my new joint. For the record, I have not grown a new joint. This is an existing body part that has started clicking when I run. It's on the back side of my leg (is that still called the knee back there?). Does anyone know what might be causing this clicking and if there's anything I can do to fix it? It doesn't happen when I'm on the elliptical.
