Infrared red with massage has been proven for years, it works! it heals the tissues %26 muscles from inside the skin. It sooths pain %26 %26 promotes blood flow. I couldn't walk because of a tendon pulled on the bottom if my foot from being flat footed. Using the infrared strengthened my muscles within weeks. My podiatrist was in awe of the recovery time. He tood me that type of injuries takes closer to 4-6 months. Another friend fractured his foot, could not walk. I gave him this wrap to help with pain %26 swelling. Within 4 weeks he his into his regular shoes %26 walking without pain. I can't say this will work for everyone, but trying it is better than not. I hole heartily recommend infrared heat.
