Hot Cold Pack for Neck and Shoulder is ideal for areas that are prone to pain and tension. Our product uses the Thermotherapy principles to alleviate pain through the application of heat and cold. Heating promotes circulation and relaxation of muscle spasms, while cooling reduces sharp pain and swelling. Athletes, people who work with computers, or even ordinary people who are suffering from neck and shoulder pain—this pack is perfect for everyone. The shape of the pouch allows it to comfortably wrap around your neck, which relieves pain in the targeted areas during usage.
