These mini gel packs by Life and Limb Gel measure 3" x 5". They are suitable for both hot and cold therapy, and are great for keeping food cold in a cooler. Wherever you need relief, Life and Limb Gel offers state-of-the art hot and cold gel packs that are sure to meet your needs and budget. Hot therapy can help soothe and relax sore muscles, can reduce arthritic joint pain, and can stimulate blood flow to accelerate the healing process. Cold therapy is an excellent way to treat acute sprains and strains and treat muscle tension, pain, and spasm. Cold therapy also helps reduce injury-related pain and swelling. These products are affordable for individual use but the high quality craftsmanship and ease of washing, sanitizing, and reusing make them ideal for the medical professional.
