Gilbert Arenas said on Friday that his knee's comfort level and flexion fluctuates daily, depending on the weather conditions.
Arenas was felling great on Friday in Chicago, but it felt awful on Wednesday in Indianapolis.
"Really high humidity and places that's cold, it gets in my joints," Arenas said. "You know how they say, 'I know when it's going to rain'? Well, I know when it's raining.
"In Indiana, it was bad. The joint swells, so it stays stiff, so I can't really get the flexion that I need. But as soon as we landed here, it was fine."
Orlando coach Stan Van Gundy said he thinks Arenas' knee will "correct over time, but it'll take some time."
