Thanks, Irish! Actually, it's not swollen right now, and has gone down after I've gone to bed. I think it's the crappy loveseat I sit on when I use the computer. The cushions are in poor shape, sunk, and the loveseat is old. We're getting new furniture when we move (well, shortly after we move). I think my boyfriend's right, in that it's the loveseat and just fluid retention.
