Introduction

A sprained ankle refers to an ankle joint injury. Generally, after an ankle sprain, one may choose either heat or cold therapy. It is recommended to use cold therapy within the first 48 hours after the injury and switch to heat therapy after 48 hours. Patients should promptly go to the hospital for examination and receive symptomatic treatment under a doctor's guidance. During recovery, it is important to timely replenish nutrients for the body.

Ankle sprain refers to a sprained ankle joint. Typically, either hot or cold compresses can be used following an ankle sprain. It is recommended to use a cold compress within the first 48 hours after the injury and switch to a hot compress after this period. Patients should seek medical attention promptly and undergo symptomatic treatment under a physician's guidance. Detailed explanations are as follows:

Within the first 48 hours after an ankle sprain, a cold compress is recommended. Cold therapy reduces local blood circulation by constricting blood vessels, thereby decreasing swelling and pain. It also lowers the metabolic rate of the affected tissue, reducing the release of inflammatory mediators, which helps control the progression of inflammation. A cold compress can be applied using a towel soaked in cold water or an ice pack, but care should be taken to avoid excessively low temperatures that could cause frostbite.

More than 48 hours after the ankle sprain, when swelling and inflammation begin to subside, a hot compress may be used. Heat therapy dilates blood vessels, enhancing local blood circulation, which promotes the absorption and resolution of inflammation and accelerates tissue repair and healing. Additionally, heat therapy can relieve muscle tension and pain, improving joint flexibility. A hot compress can be applied using a hot water bag or a towel soaked in hot water, but caution should be taken to avoid burns.

During the recovery period, it is important to ensure adequate nutrition for the body. Consuming nutrient-rich foods such as eggs and pork ribs appropriately can aid in recovery.
