Testing My Knee

Decided to test my knee today on a short run. After the 12 inches of snow that we got two days ago, I wasn't really excited to run in the snow or cold. So the treadmill won out. Immediately upon starting to run, I had pain in the knee. Walking does not hurt, but running at 4.7 mph does. So, I did a very slow jog, and stopped to stretch every 1/2 mile. It's just going take time, and a lot of stretching, ice, ultrasound, and patience for this to heal, just like my left knee did earlier this year. I still don't know why I'm prone to ITBS anyhow. It sucks.  The knee does not hurt otherwise during the day, or when walking, only when running.
