Tried a different painkiller today, and a knee-strap (which generally is just whistling in the dark), and on the whole felt much better. It's still pear-shaped (not literally) and I need to see the ortho (Tuesday can't come soon enough) but it was fine for an hour-and-change of hockey.
Aside from that, I played much better than the past few weeks. I let in some stupid goals (etc, etc.) but a few different people remarked on improved quickness - I was all over the puck and tracking it, I thought, very well. There were situations where previously I would have lost track but I didn't this time. I've been working very hard (or at least, dutifully) on hand-eye coordination with a tennis ball, a wall, and any spare minutes I have. I try to do like 5-10 minutes a day (on average - gym days it's more, school days I have to squeeze it in during breaks). Just variations on a theme - throw, catch, repeat, throw with one hand, catch with the other, throw-catch with one hand, do all of it on one leg, do it on the other leg, etc. Surprising what a difference that's made. I'm looking forward to scheduling a lesson for this week after seeing the ortho. It's probably just flaring arthritis and I'm due for a couple of cortisone shots. Fingers crossed.
