Ice packs are often used after injuries such as an ankle sprain have occurred. Applying an ice pack early and often for the first 48 hours will help minimize swelling. Decreasing swelling around an injury will help to control the pain.
Ice treatments may also be used for chronic conditions, such as overuse injuries in athletes. In this case, ice the injured area after activity to help control inflammation. Never ice a chronic injury before activity.
Heat TreatmentHeat treatments should be used for chronic conditions to help relax and loosen tissues, and to stimulate blood flow to the area. Use heat treatments for chronic conditions, such as overuse injuries, before participating in activities.
Do not use heat treatments after activity, and do not use heat after an acute injury. Heating tissues can be accomplished using a heating pad, or even a hot, wet towel. When using heat treatments, be very careful to use a moderate heat for a limited time to avoid burns. Never leave heating pads or towels on for extended periods of time, or while sleeping.
