Homedics Gel Compression Shoulder Back Sleeve Keep feelings of tension at bay with the Homedics Hot and Cold Relief Gel Shoulder Support. Designed to help reduce discomfort around the shoulder and top of your back, this shoulder support makes for an innovative alternative to standard hot patches and ice packs. Filled with pliable gel, that contours to the shape of your shoulder, upper back and upper arm, you can enjoy soothing relief as you go about your day. For cold relief from stress and soreness that lasts for 30 minutes, place the support in your freezer for up to two hours before use. If you'd prefer a warm treatment, simply heat the support in the microwave for 40 seconds (add 10 second intervals for extra warmth) to enjoy 10 minutes of soothing heat.
