By Larry Kramer. Ice packs are used sometimes to treat muscle strains or sprains in different parts of the body. These packs if incorrectly used, can cause skin burns which may vary from mild such as first degree burns or more severe such as second and third degree burns.
Ice is useful for reducing pain and inflammation associated with an acute injury. Icing is most effective if done the first couple of days after the injury has occurred. You can apply ice for 20 minutes at a time and as frequently as every hour. If you prefer, apply it four to eight times a day.
