Sister, your hand is hurt. Playing volleyball, my hand is swollen. I asked her if her hands were better. She said, well, just blue and purple ... what should I say ... I'm chasing.

Well, first of all, don't worry, because I also play volleyball. Second, tell her to apply hot water and gently rub her arm if possible! Topical liniment doesn't work. You can buy her a bottle of hand cream and tell her to take good care of herself. I hope you can feel at ease.
