in lacrosse practice. Another player collided with him and hit the side of difficult child 1's knee with the front of his knee. The other player was fine, but difficult child 1 could barely walk. He's had ice on it tonight and is gimping around. The side of the knee is a bit swollen -- doesn't look as bad as some frontal impact swelling I've seen and had myself. I'm just worried about the joint in general. I may take him in to get checked out tomorrow. We were supposed to go for his first ski trip on Tuesday, but that may not happen now.
