I have this weird knee thing going on right now. It started about a week ago behind my right knee. I figured that I somehow had hyperextended my right leg during last Tuesday's ride to work. It wasn't a sharp pain. I didn't feel anything pop when it happened. In fact, I didn't even feel it happen. This dull pain just sort of appeared.
I did swim on Wednesday but skipped Thursday morning's run. However, I did ride to work on Thursday and Friday. Liking active rest, I did make the rides easy ones. The pain was still there on Saturday but it had moved to the outer edge of my knee. It now felt like a bruise (i.e. tender to the touch) but there was no bruise there. I did a five-mile run Saturday morning with no problems. Still wanting to rest it, though, I skipped Sunday's planned bike-run brick workout.
I swam on Monday and today, rode to work yesterday, and will, likely, ride to work tomorrow. We'll see about Friday. This weekend I had planned an easy run on Saturday and and easy bike on Sunday. We'll see. Since I am taking next week off from training for the big race, I am hoping that that will keep me healthy and heal me up.
I suspect this was caused by a change I made to the cleats on my cycling shoes. I rotated them a bit to point my toes out a bit. I did this a few weeks ago and hadn't had any problems. My thinking is that I did something (unclip, etc.) that, because my feet were in a funky angle, caused a little strain. I have un-funked my cleats back to their previous positions and we'll see if that helps me get back on track.
Then again, because the pain has been moving, maybe I have worms in my knee.
