From jarred knees to tweaked shoulders, twisted ankles to bruised elbows, sports injuries (and such like) can lead to bruising, swelling and pain. Enter the trusty ice pack to reduce the inflammation and help the area on its way to recovery. At the other end of the scale, heat treatment can help to relax and warm up stiff muscles; easing lower back pain and even helping prepare for exercise when re-entering a regime following injury.
