Here's How: 1  Get the ice on quickly. Icing is most effective in the immediate time period following an injury. 2  Perform an ice massage..

The reason for icing is to decrease inflammation and/or pain in the affected area. The way it works is the ice lowers body temperature around the affected area, decreasing blood flow which in turn helps to reduce swelling.
