First, distinguish the severity of the injury. If you can stand with a load and barely walk after spraining your foot, it means that the sprain is light and you can handle it yourself; If you can't stand or move after spraining your ankle, press the painful place on the bone and swell up gradually, which means that you may have sprained the bone, so you should go to the hospital for a film immediately.

Correct use of hot compress and cold compress. At the beginning of the sprain, the broken small blood vessel was bleeding. At this time, cold compress can be used to contract and coagulate the blood vessels and control the development of the injury. After 24 hours, the bleeding of the ruptured blood vessel stopped. At this time, hot compress can be used to promote the dissipation of congestion around the sprain.

Third, press the sprained part correctly. In the early stage of sprain, it is better to keep pressing hematoma. After 24 hours, do the kneading method, with swelling as the center, and knead in all directions around.
