Cold therapy is mostly utilized in sports where muscle injuries are a regular occurrence. Cold therapy packs are now a standard part of first aid kits carried to sporting events. The cold therapy gel treatment can be very useful for sprains or injuries that happen at home also. This is why every home should have such a product in the refrigerator or freezer ready to be used when needed. Treating injuries this way is not expensive, easy to apply, and most importantly achieves the desired end result - that of seeing the injured muscle restored to its previous optimum functioning.
