Cold therapy is a time-tested method for obtaining relief from pain, especially when you are injured, strain a muscle, or are recovering from surgery. This technique is part of the RICE (Rest, Ice, Compression, Elevation) method for healing and is widely used across the world. One of the common ways to utilize cold therapy is with an ice pack held in place with an elastic bandage. 

Advances in technology have made it easier to apply cold therapy when you need it. Cold therapy machines work by circulating water through an ice reservoir. The reservoir connects to a wrap that provides the element of compression, which may help reduce swelling. With a cold therapy unit, you get the combined benefits of therapeutic cold and targeted pressure to aid in your healing.
