Hot and cold compresses are needed after face bump swelling, but cold compresses should be applied first and then hot compresses. Because the cold compress with ice bag can make local capillary constriction, reduce local congestion and protein-rich exudate exudation, also can reduce the inflammatory media to local convergence, reduce pain. After two days and then switch to hot compresses, hot water bags or hand warmers can be used to promote the absorption of inflammatory mediators in the swollen area, promote the absorption of tissue fluid, promote the absorption of bruising as soon as possible, and restore normal appearance as soon as possible. This time can also be combined with drinking chrysanthemum tea, honeysuckle tea, etc. to clear the heat and fire. The time of hot compress can be extended appropriately, about a week. If the swelling of the face is serious you need to go to the hospital first to check to prevent any serious tissue damage or even swelling caused by cranial trauma. During the observation period, if there is serious discomfort also need to promptly seek medical attention.
