One of the simplest, safest and most effective self care techniques for injuries or painful musculoskeletal conditions is ice. It is used initially for First Aid and at later stages for the rehabilitation of injuries or chronic problems.
Ice initially constricts local blood vessels and decreases tissue temperature. It then dilates deep tissue vessels and increases tissue temperature. These two responses alternate and are called the Hurting Response. The effects of this response are to decrease swelling, tissue damage, blood clot formation, inflammation, muscle spasm and pain; and to increase circulation, stimulation and strength. It also promotes healing by speeding nutrients to the area while removing waste.
Since the damage caused by uncontrolled swelling is often as great or greater than that of the initial injury, and because healing time increases in direct proportion to the amount of swelling, it is very important to use ice immediately after an injury.

During treatment with ice you will feel the following stages:
CAUTION: STOP as soon as numbness is achieved. Maximum ice time is 20-30 minutes at a sitting. Ice therapy is very safe when used within the treatment time recommendations. It is NOT recommended:
