Designed to be used as both a cold pack to alleviate swelling and pain, and a hot pack to ease muscle aches and stiffness, it provides flexible treatment options. The pack is reusable, making it a practical and eco-friendly choice. Its flexible design ensures it remains pliable and conforms to body contours, even when frozen, for comfortable application. Easy to use, it can be heated in the microwave or chilled in the freezer, providing convenient and effective relief. Built with durable materials, it is designed to withstand repeated use, making it a reliable addition to any pain management routine. Drug-free Thermotherapy: Cold therapy is recommended for conditions such as tension headaches, fever relief, sprains (e.g., ankle), and contusion swelling (e.g., knee). Heat therapy is suggested for issues like stiff neck or shoulders, lower back pain, wrist arthritis (as an adjunct for rheumatoid arthritis without acute inflammation), as a body or bed warmer, period pain, and general muscle stiffness, including knee discomfort.
