A cold Medi-Gelpak works by constricting blood vessels and reducing blood flow to the injured area. This reduces swelling and numbs the pain. Our Medical Gel Pack also stays soft and flexible when frozen to wrap around body parts.
A warm Medi-Gelpak dilates the blood vessels, promotes blood flow and helps muscle relax. Commonly used for chronic pain relief. Our Medical Gel Pack can be heated through a microwave or hot water.
