Cryotherapy simply means the use of cold as a therapy. Applying cold to the area reduces the amount of fluid flowing into the tissues and also slows the release of chemicals that cause pain and inflammation. Cold also decreases the activity of cells in order to reduce the amount of swelling at the injury site which means that it slows down the inflammation reaction. In the acute stage of injury it gives relief to the pain and reduces swelling. A cold pack or ice massage is usually applied after the treatment or used as home treatment.
