Cold Therapy
Cold therapy with ice is the best immediate treatment for acute injuries because it can reduce swelling and pain. Ice is a vasoconstrictor (causes the blood vessels to narrow) and it limits bleeding at the injury site. Apply ice to the affected area for 10 to 15 minutes at a time. Allow the skin temperature to return to normal before icing a second or third time. You can ice an acute injury several times a day.
Cold therapy is also helpful in treating some overuse injuries or chronic pain in athletes. An athlete who has chronic knee pain that increases after running may want to ice the injured area after each run to reduce or prevent inflammation. Never ice a chronic injury before exercise.
