The Flex Pain Patch provides drug-free pain relief within minutes anywhere on the body for mild to severe and even chronic pain. Designed to work with your nervous system, the reusable flexible patches can be worn 24-7 for up to one month and are made with raw conducting elements, like copper, so they don't smell like other pain relief products. Because the patches lower your pain levels, they can also potentially help improve your sleep quality and your daily function.
