Both cold and hot compresses are required after a waist sprain, which is mainly different from the time period of the waist sprain. Cold compress treatment is required within 48 hours of a waist sprain. Cold compress treatment can reduce the swelling of the injured part of the waist, reduce the exudation of interstitial fluid, and reduce the symptoms of waist pain. When the waist is sprained for 48 hours, the waist heating pad should be used for hot compress treatment. At this time, the hot compress can quickly reduce the swelling of the waist, and gradually absorb the exudation of the waist, and can also promote the gradual repair of the soft tissue of the waist injury. At the same time, pay attention to the warmth of the waist in the later stage.
