Manufacturer: Southwest Technologies Elasto-Gel Hot/Cold Pack (6" x 8") is a versatile and effective therapy solution designed to provide both heat and cold treatments for pain relief, muscle relaxation, and inflammation reduction. This compact pack is ideal for targeting smaller or more localized areas of the body, such as the neck, wrists, elbows, knees, or small muscle groups. Features: -When heated, the Elasto-Gel pack offers moist heat, which can penetrate deeper into tissues than dry heat. This is especially helpful for relaxing muscles, improving blood circulation, and reducing stiffness. Moist heat is ideal for treating chronic pain, muscle tension, or joint stiffness. -When cooled in the freezer, the pack provides effective cold therapy to reduce inflammation, numb pain, and alleviate swelling. Cold therapy is great for managing acute injuries, sprains, strains, and swelling from surgery. -The pack is 6 x 8 inches, making it perfect for treating localized pain or smaller body areas. It's particularly effective for use on joints, wrists, knees, elbows, or other small muscle groups, providing concentrated treatment where its most needed. The Elasto-Gel pack is designed to maintain its temperature for 20-40 minutes, allowing for extended sessions of effective therapy without the need for constant reheating or refreezing. The gel inside the pack retains moisture, creating soothing, moist heat when microwaved. This can help to improve the overall effectiveness of the therapy, as moist heat tends to work more deeply and efficiently on sore or tense muscles.
