Instructions for the Use of Ice

Ice is used to reduce swelling, inflammation, and irritation to nerves, resulting in reduction of pain as well as aiding the body’s natural healing processes.

It is recommended that you use a reusable flexible cold pack. If this is not available, you may use a plastic bag half-filled with crushed ice cubes, instant ice packs, or, if necessary, even a bag of frozen vegetables (lima beans work nicely!). Make sure that the ice pack is of an appropriate size and molding capacity for the affected body part.

Place the ice on the area of pain, or in an area specified by Dr. Johnson. Never place the ice directly on the skin: frozen ice packs are often lower than 32 degrees Fahrenheit, and can quickly cause frostbite. Use one layer of thin clothing or a damp paper towel between the ice and your skin.

Leave the ice on for 15 minutes.

NOTE: Longer is NOT better with ice. Even after removing the ice, the local tissues will, amazingly, continue to get colder. If the ice remains in place for 30 minutes, the body reacts by increasing blood flow to the area to "save" the tissues from frostbite. However, the increased blood results in swelling and the return of inflammation.

Also, do not lie on your ice pack. Ice plus compression equals significantly lower temperatures, and puts you, again, in danger of frostbite.

Apply the ice every two hours during the day, until otherwise instructed by Dr. Johnson.
