My knee has been hurting all night tonight. I've never really had any knee problems before, so I'm not sure if this is normal or what. It kind of feels like I've been sitting cross legged for a REALLY long period of time, and then when you stand up and try to walk, your knee is a little creaky and achy. It's not stabbing pain or anything, but it doesn't seem to be going away either. Anyway, just wanted to make a note of this!
