After an ankle sprain, whether it is a ligament or bone injury, there will be bleeding at the injury site, and the skin integrity exists only when the bleeding is wrapped in soft tissue. In the early stage of ankle sprain bleeding should be considered immediately to apply ice to reduce bleeding and at the same time reduce swelling; in the later stage when bruising has been formed and absorbed, hot compresses should be applied to promote the absorption of bruising. The whole process must be careful not to walk on the ground, and if necessary, go to the hospital for a radiograph to exclude bone problems, and serious bone problems may require surgery to solve.
