It is normal to play basketball normally, and it is normal to be buffered. Generally, I stepped on someone else's foot when I jumped up and fell down, and then I sprained my ankle, that is, my ankle was pitted. However, in order to prevent the opposing players from playing, some players often deliberately step on their feet, and it is not easy to distinguish whether they are intentional or unintentional in judgment. This is an immoral behavior and violates the sportsmanship.
When you meet a mat, take a rest and see if you can walk normally. I can't walk with a broken bone. I have to go to the hospital for medical treatment. If you can walk, it's not too serious. First, use cold water to reduce edema, or even better, ice cubes. When it is cold, blood vessels will contract, which will reduce edema. After 24 hours, the edema rises and needs hot compress. Put it on a hot towel with boiling water, the heated blood vessels will stretch and promote blood circulation. It will be all right soon.
