Philips created PulseRelief to target those suffering from musculoskeletal pain, but its other high-tech pain reliever called BlueTouch was made to relieve muscular back pain, in particular. If BlueTouch (below) looks familiar, it's because an older version has long been available for sale. The device shines blue LED lights against your skin, which Philips claims can induce the body to release Nitric Oxide that increases blood flow and encourages the natural healing process. Like PulseRelief, this iteration comes with a phone app, where you can choose from various treatments. Both devices will be out in stores later this September and online in November, but make sure to read up on the medical claims behind the devices (the old BlueTouch had its share of doubters) and consult your doctor before getting one.
