I have a question....

Background. Last Thursday, I did something to my left knee-- I have no idea what. I was sitting with my leg propped up and when I stood up it hurt like crazy--I could barely stand, let alone move. Eventually it got better though it was kind of achy.

Friday it was feeling better. I went to the gym for light exercise (walked on treadmill) and then got invited to play soccer, so I did. I warmed up, played hard, was feeling fine. I figured I would be a bit sore the next day from the exercise, but no big deal.

Except my knee was REALLY sore Saturday. As in barely able to move sore. The rest of my muscles were sore--especially my thighs--but in a more normal manner. So I took it easy.

But my knee is still pretty sore. It's not as bad, but it stiffens up if I sit down for any length of time and even when it warms up it hurts and sometimes it's not very stable--not sure how else to describe it, but sometimes it doesn't want to support my weight. It hurts a bit in the knee cap, but mostly it hurts around and behind the knee, and into my upper calf.

Could I have strained a muscle that supports the knee or something? Should I do something more than naproxen, rest, and ice?

I was just getting back into a regular exercise routine and this has really poked holes in it--unless it's much better tomorrow, I probably will break a 14 week streak (130 minutes a week) and as it is I won't be able to make my monthly goals for September. But I would rather restart my streaks and worry about next months goals than really mess my knee up.

*edit* I remember after I wrote this blog that I did wrench my knee a bit while playing soccer--I remember turning and feeling it and thinking that I'd hurt it, but it didn't hurt and I forgot about it. But adrenaline can do that. So I probably have a mild sprain, which can take some time to heal.
